Home › Math & Conversions › Core Math & Algebra › Trig Identity Explorer Trig Identity Explorer & Checker Browse the most important trigonometric identities in one structured cheat sheet and use the interactive checker to test your own trig identities numerically. All trigonometric functions are evaluated in radians. Use x as the variable. Trig identity checker Enter a candidate identity in terms of x . The tool evaluates both sides at several values of x (in radians) and checks whether they agree within a small numerical tolerance. Left-hand side (LHS) Right-hand side (RHS) Supported functions: sin , cos , tan , sec , csc , cot , asin , acos , atan , sqrt , abs , log , ln , exp , and constant pi . Check identity numerically Clear The numerical check report will appear here. The tool samples several values of x in radians and compares LHS(x) and RHS(x). Basic & Pythagorean Sum
