Some Things to Memorize
-
Trigonometric Identities
-
Pythagoras’ Theorem: h2 = p2 + b2
-
Sin(θ) = p / h
-
Cos(θ) = b / h
-
Tan(θ) = Sin(θ)⁄Cos(θ) = p / b
-
Cosec(θ) = 1⁄Sin(θ) = h / p
-
Sec(θ) = 1⁄Cos(θ) = h / b
-
Cot(θ) = 1⁄Tan(θ) = b / p
-
Sin2(θ) + Cos2(θ) = p2/h2 + b2/h2 = (p2+b2)/h2 = h2/h2 = 1
