How To Solve Trigonometric Equations 8 Steps With Pictures
To solve a trig equation, transform it into one or many basic trig equations. Solving trig equations finally results in solving 4 types of basic trig equations. To transform a given trig equation into basic trig ones, use common algebraic transformations (factoring, common factor, polynomial identities. . . ), definitions and properties of trig functions, and trig identities. There are about 31, among them the last 14 trig identities, from 19 to 31, are called Transformation Identities, since they are used in the transformation of trig equations....
