cos (90° – x) = sin x : tan (90° – x) = cot x: cot (90° – x) = tan x : sec (90° – x) = csc x: csc (90° – x) = sec x 1 Trigonometric Identities you must remember The “big three” trigonometric identities are sin2 t+cos2 t = 1 (1) sin(A+B) = sinAcosB +cosAsinB (2) cos(A+B) = cosAcosB −sinAsinB (3) Using these we can derive many other identities. Even if we commit the other useful identities to memory, these three will help be sure that our signs are Identities Proving Identities Trig Equations Trig Inequalities Evaluate Functions Simplify Statistics Arithmetic Mean Geometric Mean Quadratic Mean Median Mode Order Minimum Maximum Probability Mid-Range Range Standard Deviation Variance Lower Quartile Upper Quartile Interquartile Range Midhinge sin(x) cos(x) sin(x) sin ( x) cos ( x) sin ( x) Cancel the common factor of sin(x) sin ( x). cos(x) cos ( x) Because the two sides have been shown to be equivalent, the equation is an identity. sin(x)cot(x) = cos(x) sin ( x) cot ( x) = cos ( x) is an identity.
