## What sine means?

1: the trigonometric function that for an acute angle is the ratio between the leg opposite the angle when it is considered part of a right triangle and the hypotenuse.

## What is sin used for?

sin cos and tan are basically just functions that relate an angle with a ratio of two sides in a right triangle. Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse.

## Is Sine a number?

## What is the formula of Cos?

The law of cosines generalizes the Pythagorean formula to all triangles. It says that c^{2}, the square of one side of the triangle, is equal to a^{2} + b^{2}, the sum of the squares of the the other two sides, minus 2ab cos C, twice their product times the cosine of the opposite angle.

## How do you go from sin to cos?

All triangles have 3 angles that add to 180 degrees. Therefore, if one angle is 90 degrees we can figure out Sin Theta = Cos (90 – Theta) and Cos Theta = Sin (90 – Theta).
