How To Remember The Functions Of Sine, Cosine And Tangent

How can I remember the functions of sine, cosine and tangent?

With middle school math's tips, one of the ways to remember sine, cosine, and tangents is to firstly, remember they only apply to right triangles, and here's the way to remember. SOH, S-O-H, CAH, C-A-H, TOA, T-O-A. So for the first part of SOHCAHTOA, S-O-H, sine equals opposite over hypotenuse. For the second part, CAH, C-A-H, cosine equals adjacent over hypotenuse. For the last part, TOA, T-O-A, tangent equals opposite over adjacent. So, just to review math's sine, cosine and tangents; the sine equals opposite over hypotenuse, cosine is adjacent over hypotenuse, and tangent is opposite over adjacent.
