Trigonometry

Make a Qutubminar by folding 2 chart papers and giving it a accurate shape then paint it properly and then cut different shapes of flowers to show the steps after that put that on the plyboard so that it will be strong and heavy to hold and can be seen in the lab and then show some greenery and it will be perfect all the best friends do it properly when I have to find for it was so hard but this is my creativity so if u like this make it

A angle of 300 degrees is a reflex angle

A degree is divided into 60 minutes and each minute is divided into 60 seconds. It would mean 54 degrees and 28 minutes. You often find this nomenclature when talking about degrees of latitude and longitude.

1/2 x length x width x height

tan-1(0.5) = 26.6 degrees.

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.

A seven sided shape need not cost you anything!

The Answers community requires more information for this question. Please edit your question to include more context. The answer depends on the resistance offered by the push-rod.

You want one clamp on one side of the center of the glass and the other clamp on the other side of the center of the glass witrh both equal distance awy from the center.

That is because then both clamps take the same weight ( 1/2 each). I f they are not centered one wil carry a much higher load and also if both are on the same Sid ethe glass will not be centered.

You should put the clamps near the ends as it will easier to have it level over the greatest distance

True. You may not be able to switch numbers like 4-2=2-4 but you would say 4-2=-2+4

That is not the associative property!

The associative property requires that the order of operation can be changed without affecting the final result. This is clearly not the case with subtraction since:

(5 - 3) - 2 = 2 - 2 = 0

while

5 - (3 - 2) = 5 - 1 = 4

I think no. IT is impossible

Each angle may be used as a 'reference angle'. A 30 deg. angle in QI will have a sides, x = (sq rt 3)/2 , y= 1/2, r = 1. An angle of 150 deg (180 - 30) will create a triangle in Q2 with the same lengths except x is now negative. So if you know all trig values for 30, then change the signs for cos and tan because x is now negative and you know the values of all. Similarly for 210 deg (180+30) creates the same triangle in Q3 but both x and y values are neg. Sin and cos are neg, but tan (divide 2 neg's) is positive. In Q4 (360 - 30) creates a 330 deg angle for a triangle that is the same shape, but y is neg and x is pos so that sin and tan are neg but cos is pos.

ex: sin 30 = 1/2 (Q1), sin 150 = -1/2 (Q2), sin 210 = -1/2 (Q3), sin 330 = 1/2 (Q4)

notice only the sign (+/-) changes.

Most trig classes teach you that Q1 all trig functions are pos, Q2 sin is pos, Q3 tan is pos, Q4 cos is pos. Remember this and the 1st Quadrant values and then you can get all trig functions using the concept of a reference angle.

Yes, but it will depend on the domain.

Since sec(x) = 1/cos(x), you may find it easier to work with

y = 4/cos2(2x)

The graph will be a set of U shapes. At even multiples of pi radians (180 degrees), the U-shapes will have their minima ( = 4). At odd multiples of pi radians they will be asymptotically +infinity.

The graph of the tangent function is periodic at every point. Periodic means that the value of the function at every point is repeated after an integer multiple of the period.

It has a horizontal number line called the x axis

It has a vertical number line called the y axis

Both axes are perpendicular to each other and meet at the origin

Graphs can be plotted on it

look at an analog clock and whatever time it is you can determine if it is a right angle, acute, obtuse, or straight. look at the borders of doors or the ceiling

it is used in real life situation to fin the height of thing and in math you use it to find the length of one of the sides.

The equation x2 + y2 = 1 is the equation for the unit circle, with center at (0,0). The intersections between that circle and the lines emmanating from (0,0) having angles of 30, 45, 60, 75, and 90 degrees relative to the positive x-axis would be 30 = (0.866, 0.5), 45 = (0.707, 0.707), 60 = (0.5, 0.866), 75 = (0.259, 0.966), and 90 = (1, 0).

In each case, the x coordinate is the cosine of the angle and the y coordinate is the sine of the angle. All answers have been rounded to three significant places.

Since x is a constant (2.8) the only variable changing would be y, that means that it is a vertical line that crosses the x-axis in 2.8

If you also know its shadow then you can work out the angle of elevation
