WebbThe fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions. Angle-Sum and -Difference Identities sin (α + β) = sin (α) cos (β) + cos (α) sin (β) sin (α − β) = sin (α) cos (β) − cos (α) sin (β) WebbTo 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.
