If you have an angle then the length of the side OPPOSITE that angle divided by the length of the HYPOTENUSE. (O/H)
(HYPOTENUSE is the side opposite the 90 degree angle)
or (y/x)
and a lot of other cool ways.

arc sine is the inverse function of the sine function so if y = sin(x) then x = arcsin(y) where y belongs to [-pi/2, pi/2]. It can be calculated using the Taylor series given in the link below.
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
sine 810 = sine 90 = 1
The sine of an angle of a right triangle - which is a triangle containing one 90o angle - is calculated as the length of the side opposite the angle divided by the length of the hypotenuse. For very small values of x, sin(x) is approximately equal to x.
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
