Programmed Math/Sine

In a right angled triangle, Sine is the opposite side of the angle needed divided by hypotenuse; so: $\sin \theta ={\frac {o}{h}}$ An equation with Sine would be the following, when the opposite is equal to 5 and the hypotenuse is equal to 10: $\sin \theta ={\frac {o}{h}}$ = $\sin \theta \ ={\frac {5}{10}}=0.50$

Sine is usually used for triangle with the angle in the corner of lower point of the hypotenuse.

Sine can also be reversed, to find out the length of the sides when you have the angle already.

This can be used by going $\sin ^{-}x={\frac {2}{h}}$, where x is the angle you have, and h is the side you want to get.
