WebTo simplify a trigonometry expression, use trigonometry identities to rewrite the expression in a simpler form. Trigonometry identities are equations that involve trigonometric functions and are always true for any value of the variables. How … WebMar 17, 2024 · To simplify a square root, we factor the radicand into its prime factors and group any pairs of identical factors together. Next, we take the square root of each perfect square factor and multiply them together outside the radical symbol. The remaining factors are left inside the radical.
