-
Divide the length of the hypotenuse by the opposing side.
-
If you know the lengths of the three sides of the triangle, the sine of angle X is the ratio of the length of the triangle leg opposite angle X to the length of the hypotenuse. http://en.wikipedia.org/wiki/Sine#Right_triangle_definitions

if i remember it correctly, right angle has a 90 degree angle and that is a constant with sin 0. hehehe...
-
The sine is the side opposite the angle divided by the hypotenuse of the triangle.
-
Opposite side divided by hypotenuse.

6-17-2017 Trigonometry is based on a picture of a circle with the radius making an angle with the x axis. You carry this picture in your head, not your calculator. Trig is mostly imagination and the rest memorization. Remember Chief SohCahToa -- Sin = Opposite/Hypotenuse -- Cosine = adjacent/Hypotenuse -- Tangent = Opposite/Adjacent -- Also memorize -- Sec = 1/Cos -- Csc = 1/Sin -- Cot = 1/Tan
