Trigonometry

The cosine of theta is adjacent over hypotenuse, given a right triangle, theta not being the 90 degree angle, adjacent not being the hypotenuse, and theta being the angle between adjacent and hypotenuse.

In a unit triangle, i.e. in a unit circle circumscribed with radius one, and theta and the center of the circle at the origin, cosine of theta is X.

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 degrees (1291-3x360=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.

The point (x, y) is moved to (x+pi/4, y).

Since sin(theta) = 1/cosec(theta) the first two terms simply camcel out and you are left with 1 divided by tan(theta), which is cot(theta).

The difference may be due to the thickness of the can.

There are several, what is it that you want to calculate?

The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.

First draw the graph.

Label A S T C according to the order of plane.

Draw a 90 degree angle.

You see it's between All and Sin, so the answer is 0

Draw 270 degree angle.

You see it's between Tan and Cos, so the answer is -1

And when you mix them together, 0 times -1 = 0.

By converting cosecants and secants to the equivalent sine and cosine functions. For example, csc theta is the same as 1 / sin thetha.

It is used to calculate the trajectories of projectiles and missiles.

The range is infinite in both directions.

cos(32 deg) = 0.8480 approx.

It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!

cos(A + B) = cosAcosB - sinAsinB, with A=B, cos(2A) = cos2A - sin2A, then you can use cos2A + sin2A = 1, to produce more, like: [2cos2A - 1] or [1 - 2sin2A], and others.

phi = [(1+sqrt(5)]/2 = 1.6180, the golden ratio.

cosine(phi) = -0.0472 approx.

There are an infinite number. The simplest is a sinusoid. The sine function has period 2π, so you compress it by a factor of π: f(x) = sin (πx).

tan u/2 = sin u/1+cos u

2cos2x - cosx -1 = 0

Factor:

(2cosx + 1)(cosx - 1) = 0

cosx = {-.5, 1}

x = {...0, 120, 240, 360,...} degrees

It is not clearly mentioned that whether it is the "THIRD" root we have to calculate.. or the "SQUARE ROOT THREE TIMES.. i.e the EIGHTth ROOT".. The answer posted here before was not correct in a sense that the if the question demands "third square root" which can also mean the "EIGHTth" root..

Re-edit:

It seems rather obvious that this answerer is new to wiki answers and is not in the habit of question interpretation. The question is most likely thus; " What is the cubic root of 0.125. The answer then would be...,

cubic root(0.125)

= 0.5

====( calculate the square root three times?!? sounds like a stretched interpretation )

Do you know what square root means? -_- if u know.. then u clearly know what "third square root means" .. huh -_-
