Trigonometry

Parent Category: Math and Arithmetic
Trigonometry is a field of mathematics. It is the study of triangles. Trigonometry includes planar trigonometry, spherical trigonometry, finding unknown values in triangles, trigonometric functions, and trigonometric function graphs.
Since you didn't specify which trigonometric function you're  using, I'll give you all of them.   120 in Degrees    sin120 ~ 0.87  cos120 ~ -0.5  tan120 ~ -1.73  csc120 ~ 1.15  sec120 = -2  cot120 ~ -0.58    Answer in Degrees    arctan120 ~ 89.52  arccot120 ~ 0.48   ...
Assuming that means degrees, that's the same as -30 degrees. The  sine of -30 degrees is exactly -0.5, the cosine is +root(3)/2, or  about 0.866. You can deduce the remaining trigonometric functions  from these; for example, tan(x) = sin(x) / cos(x).
It is easiest to find these using the unit circle. Assuming you  want exact values for sin, cos, and tan.    240 degrees is equal to 4[Pi]/3 radians.    cos(4[Pi]/3) and sin(4[Pi]/3) are easy to find using the unit  circle,   cos(4[Pi]/3) = -1/2   sin(4[Pi]/3) = -(Sqrt[3])/2   ...
Amongst the lay public of non-mathematicians and non-scientists, trigonometry is known chiefly for its application to measurement problems, yet is also often used in ways that are far more subtle, such as its place in the theory of music; still other uses are more technical, such as in number theory...
i34 is the complex part of the number 0+i34. The real part is 0, so this is a purely imaginary number.

Trignometry is used to calculate angles in length in carpentry.
The volume of a triangular prism can be found with the following  formula, in which a, b, and c are base sides and h is the height: V  = 0.25h(-a4 + 2(ab)2 + 2(ac)2 -  b4 + 2(bc)2 - c4)1/2
The length, or magnetude, of the vector is the square root of (6^2  + 8^2), or 10. The angle of inclination is tan-1 of (8/6), or 53.13  degrees.
To convert meters to feet, multiply by 3.281. It does not matter about the "per second squared" since that is present in both sides.

There are no pyramids with an odd number of edges.A pyramid is defined as a polygon for the base, with triangular shaped faces rising from the base's edges to a common point above the plane. As a result, the number of rising edges is always equal to the number of base edges, meaning that the total...
False. In fact, the opposite is true: all pyramids have an even number of edges.
Suppose the wall is represented by the y-axis and the ground as thex-axis. Let the position of the man be given by M = (x, y). Then, since M is the midpoint of the ladder, the base of the ladder is atA = (2x, 0). also, the point where it touches the wall is B = (0, 2y). Now, AB is the length of...
Measurements of a trigon (or triangle).
You need to be able to solve logarithms and be very good at algebra. In college, you have to be able to do college level algebra before you can take trig.
The area of a triangle with two sides equal to 1 foot and the angle between those two sides equal to 45 degrees is 0.354 square feet. Draw a triangle, one side of length 1, from the origin to the right along the x axis. The second side, also of length 1, goes up and to the right from the origin...
Tangent (theta) is cosine / sine, or Y / X.Tangent (theta) is 40 / 58Theta = 34.6 degreesSince we are dividing cosine by sine, the hypotenuse does not matter as it cancels out.

First of all, it is pi, a letter of the Greek alphabet, not pie! cot(x) + sqrt(3) = 0 cot(x) = -sqrt(3) tan(x) = -1/sqrt(3) The principal value is x = -pi/6 c . So the solutions are (-pi/6 + k*pi) radians where k is an integer: that is k = 1 => 5*pi/6 k = 2 => 11*pi/6 k = 3 => 17*pi/6
Tangent(theta) is sine over cosine, or y over x. x is 120. Theta is 32 and 37. y1 is height of cliff, and y2 is height of cliff plus flagpole. Tan(32) = y1 / 120, so y1 = 120 tan(32) = 75. Tan(37) = y2 / 120, so y2 = 120 tan(37) = 90. Height of flagpole is y2 - y1 = 90 - 75 = 15.All results...
Cosine(42 radians) = -0.399985Cosine(42 degrees) = 0.743146
Cosine(84 radians) = -0.680023Cosine(84 degrees) = 0.104528
Sine and cosine are cofunctions, which means that their angles are  complementary. Consequently, sin (90° - x) = cos x. Secant is the  reciprocal of cosine so that sec x = 1/(cos x). Knowing these  properties of trigonometric functions, among others, will really  help you in other advance math...
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
3rd quadrant. The four 90 degree quadrants together formed 360 degrees. When a given angle is greater than 360 degrees, subtract 360 from it till a value smaller than 360 is obtained. In this way, we can determine the quadrant in which the given angle lies.   Here the final angle obtained is 211...
YES! If you can't do algebra, you won't last ten seconds in trigonometry. It basically is algebra, just using equations within equations.
it is hard if you don't get it or if you didn't study. it will be easy if you study it and you get everything.
A periodic wave done using a rope is for example a sine wave. It is the form of Simple Harmonic Motion, and traces the equation y = sin(x) where y=1 and -1 are the peaks.
cos(195) = cos(180 + 15) = cos(180)*cos(15) - sin(180)*sin(15) = -1*cos(15) - 0*sim(15) = -cos(15) = -cos(60 - 45) = -[cos(60)*cos(45) + sin(60)*sin(45)] = -(1/2)*sqrt(2)/2 - sqrt(3)/2*sqrt(2)/2 = - 1/4*sqrt(2)*(1 + sqrt3) or -1/4*[sqrt(2) + sqrt(6)]
d theta divided by 4.28 is not an equation or inequality: it is an expression. An expression cannot be solved.
Trigonometry goes back to ancient times. The first trigonometrictable is attributed to Hipparchus of Nicaea.

BSW is a Bachelor's in Social Work.     A CAS is a Certificate of Advanced Study. It usually refers to a graduate school degree above the Masters level. It is not to be confused with a CERT degree.
It's 1/2 of sin(2 theta) .
It is because the logarithm function is strictly monotonic.
It is pi, a letter of the Greek alphabet, not pie!. sin(3*pi/4) = 1/sqrt(2) = sqrt(2)/2
Trigonometry mainly but also geometry, algebra.
Euler's formula states that, for any real number x, eix = cos x + i sin x, where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine, respectively. The argument x is given in radians.Please see the related link below for...
If the 3 sides are x, y and z then let s = (x+y+z)/2 Area = sqrt[s*(s-x)*(s-y)*(s-z)] sq cm.
I have no idea what a "corrandant" is, but I suspect that the answer to the question is NO.
A tangent refers to the way in which a curve is measured. The amount of deviation from the segment line is measures, then a formula applied to find the tangent.

Negative cosine f(x) = sin(x) f'(x) = -cos(x)
Use Pythagorean theorem if you have a right triangle with legs a and b and hypotenuse c. a^2+b^2=c^2 a=sqrt(c^2-b^2) it is possible to find b and c in a similar way.
sin^2 (feta) + cos^2 (feta) = 1sin (feta) / cos (feta) = tan (feta)

  Get a cup or bottle somethig round orrr... you can stick a hole in the middle with a thumbtack in it with string on the thubtack conected to the pen (or pencil) and go around:)
sec 2 (x) - tan 2 (x) = 1/cos 2 (x) - sin 2 (x)/cos 2 (x) = (1 - sin 2 (x)) / cos 2 (x) = cos 2 (x) / cos 2 (x) = 1
The wind correction angle for a true course of 30 degrees, with an airspeed of 300, with a wind direction of 90, and with a wind speed of 50, is -8.3 degrees. The indicated course must then be 21.7 degrees.CCORRECTION = sin-1 (VWIND sin (CWIND - CACTUAL) / VINDICATED)
Flight engineers need to calculate how they will get from one place to another. Sounds simple yet they have to take in account their speed, distance, and direction along with the speed and direction of wind. Wind plays an important role in how and when a plane will arrive where it is needed to. this...
Trigonometry is engineering math, but If you are going to study something in physics, or science, (basically this is "applied science"), you will need lots of calculus.calculus appears a lot in "Stargate".
The obvious answer is the relationships between the sides and angles of triangles.. Waves in the sea are an example of a sine wave. Tidal Experts and Meterologists alike use sine waves to help predict tides. Music will also emit waves that may often look like a sine wave and pure notes will look...

I've made a chart in google docs, you can check it in the realted links below.
The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin
largest is lies opposite to the largest side , so the largest angle is the angle which is opposite to the 23.8cm side. let a=11.3 ,b=23.8 and c=21.7 ,then the largest angle cosB=(a2+c2 -b2)/2ac ,here the largest angle is B
0.790 radians (45.2 degrees) and 2.352 radians (134.8 degrees).
by using x instead of theta (to make it easier to type), 4sinxcosx can be simplified to 2sin2x.
It means for any right angle triangle:-sine = opposte/hypotenusecosine = adjacent/hypotenusetangent = opposite/adjacent
because we use it to calculate/measure things in science for example we use maths to calculate the distance of stars from the earth
you use the the 3 trigonometry functions ,. sin=opposite divided by hypotenuse. cos=adjacent divided by hypotenuse. tan=opposite divided by adjacent. these are used to work out angles and side lengths in right angle triangles only!!!. sine,cosine,tangent. :)
