Trigonometry

Volume = Area of the base X height of prism. This formula works for all prisms, not just triangular prisms.

Area of a triangle = height of triangle X 1/2 X base of triangle.

Theta is most often used to represent unknown angles, especially in the study of trigonometry. Theta represents an angle in degrees, but not in radians.

---------------------------------------

Theta (θ) is a Greek letter, typically denoting an unknown angle. Depending on the context of the problem, it could be in degrees or radians.

trigonometry is very imr

Equilateral triangles have, by definition, 3 equal sides. This means they also have 3 equal angles (i.e. they are equiangular) with each angle measuring 60 degrees. They have 3 lines of symmetry from each vertex to the midpoint of the opposite side. These lines are the medians, perpendicular bisectors, altitudes, and angle bisectors of the triangle. The point where these three lines intersect is the centroid, incenter, circumcenter, and orthocenter of the triangle. The area of an equilateral triangle is sqrt(3)/4*s where s is the side length of the triangle.

First we look at the double-angle identity of cos2x.

We know that:

cos2x = cos^2x - sin^2x

cos2x = [1-sin^2x] - sin^2x.............. (From sin^2x + cos^2x = 1, cos^2x = 1 - sin^2x)

Therefore:

cos2x = 1 - 2sin^2x

2sin^2x = 1 - cos2x

sin^2x = 1/2(1-cos2x)

sin^2x = 1/2 - cos2x/2

And intergrating, we get:

x/2 - sin2x/4 + c...................(Integral of cos2x = 1/2sin2x; and c is a constant)

2.95 = 2 and 95 hundredths = 2 95/100 which reduces to 2 19/20

The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle

The hypotenuse is the side of a right triangle opposite the right angle. The legs are the other two sides which form the right angle.

To convert from decimal to percentage, you times 100.

2.3 * 100 = 230%

Depending on your career, you may or may not need trigonometry. If your job does not require a lot of math, it is unlikely that you will use trigonometry very often, however, this is not a reason not to study it. The skills and discipline developed in your trigoometry class will help you no matter what career you choose.

Basic trigonometry - angles or side-lengths of right-angled triangles - is quite common in many practical applications, and not just professionally.

Surveying uses the more complex, as well as basic, trig rules.

However, trigonometry as such is found in all manner of fields. For example, in electronics, sound & vibration studies, analysing wave behaviour and characteristics is very largely trigonometrical because the "shape" of a basic sound-wave, simple alternating-current electricity or indeed ocean swell is a sine function.

Trigonometry is really useful in life. If you want to be and engineer, architect, or builder, trig. is useful. If you say that a right triangle has an angle degree of 30 degrees, and the side opposite the angle is 10 ft, you can conclude that the hypotenuse is 20 ft. Trig. also states that any right triangle with a 45 degree angle has a ratio of .707106781184562. the ratio( sine) is 1 divided by the square root of 2, of the square root of 2 divided by to. Trust me, it's easier that it sounds

The x-and the y-axes of the two dimensional Cartesian coordinate system divide the plane in four. Each of these is a quadrant.

Trigonometry is used in design of everything from buildings to instruments to appliances. It is also used in electronics, acoustics, EM radiation, flight, navigation, projectile motion, and nearly every every application of waves and forces in physics and engineering.

The answer depends on what information you do have.

To change a fraction into a mixed number, divide the numerator (top number) by the denominator (bottom number) to get the whole number. The remainder is the new numerator and gets written over the same denominator. Your welcome!

Commonly known as a quadrilateral, a tetragon is a polygon with 4 (four) sides.

It is an heptagon which is also a septagon because they both have 7 sides

Trigonometry includes 12 baisic functions. Sine, Cosine, and Tangent are the three most baisic. Each of those functions has a reciprocal. Cosine's reciprocal is Secant, Sine reciprocal is Cosecant, and Tangent's reciprocal is Cotangent. Each of those six functions has an inverse funcion called Inverse Sine, Cos etc... or Arcsine, Arcosine, Arcsecant, etc.... The shorthand for each function is sin, caos, tan, sec, csc, cot. The inverses have a -1 notation like sin-1.

Trigonometry is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.

Technically there are only 4 parts to a memorandum. 1) The heading which consists of your distribution list, who it is from, the date and subject. 2) The body of the memo or text 3) the reference initial if you typed it, but didn't write it 4) notations - if necessary
