# Funny Tricks We Used In Childhood For Remembering Formulas Of Trigonometric Functions!

I always used to find Trigonometry tricky, not because it’s difficult but it’s the combination of alphabets and numbers, that too same alphabets are repeated time and again in formulas. I wasn’t aware of these memory techniques when I was in 10th standard, but I guess now I will be able to help you out a bit here.

### 1. SOH-CAH-TOA

“SOH-CAH-TOA” is a helpful method for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, Soh…           Sine = Opposite / Hypotenuse
cah…            Cosine = Adjacent / Hypotenuse
toa…            Tangent = Opposite / Adjacent

### 2. PBP/HHB

PBP/HHB is the most funniest method  and believe me for an Indian, this is the best method for remembering formulas of trigonometric functions. Here , sine equals perpendicular over hypotenuse, cosine equals base over hypotenuse, and tangent equals perpendicular over base, Sine = Perpendicular / Hypotenuse = P/H
Cosine = Base / Hypotenuse =  B/H
Tangent = Perpendicular / Base = P/B
