Question

Some students use the expression SOHCAHTOA as a memory aid for the definitions of the trigonometric functions. What does this expression stand for?

Answer 1

Sin(angle) = Opposite / Hypotenuse
Cos(angle) = Adjacent / Hypotenuse
Tan(angle) = Opposite / Adjacent

So if you have cos(60 degrees), that will equal the ratio of the leg touching (adjacent) to the angle divided by the hypotenuse.

Answer 2
