Discover 60 Precalculus Worksheet On Simplifying Trig Expressions 3 This page titled 7.1: simplifying trigonometric expressions with identities is shared under a license and was authored, remixed, and or curated by via that was edited to the style and standards of the libretexts platform. in this section, we will begin an examination of the fundamental trigonometric identities, including how we can verify them. We have seen that algebra is very important in verifying trigonometric identities, but it is just as critical in simplifying trigonometric expressions before solving. being familiar with the basic properties and formulas of algebra, such as the difference of squares formula, the perfect square formula, or substitution, will simplify the work.
