WebUse trigonometric identities to prove the identity: cotxsinx= cosx cot x sin x = cos x. … WebTo solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
