The trigonometric identities act in a similar manner to multiple passports—there are many ways to represent the same trigonometric expression. just as a spy will choose an italian passport when traveling to italy, we choose the identity that applies to the given scenario when solving a trigonometric equation. The pythagorean identities are based on the properties of a right triangle. cos2θ sin2θ = 1. 1 cot2θ = csc2θ. 1 tan2θ = sec2θ. the even odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. 21 trig identities every calculus student should know! 1. sin = 1 csc 2. csc = 1 sin 3. cos = 1 sec 4. sec = 1 cos 5.{ 6. tan = sin cos = 1 cot 7.{ 8. cot =.
