How do you know which trig function to use
WebAngle C can be found using angles of a triangle add to 180°: So C = 180° − 76° − 34° = 70° We can also find missing side lengths. The general rule is: When we know any 3 of the … WebSolving Trigonometric Equations Using Fundamental Identities. While algebra can be used to solve a number of trigonometric equations, we can also use the fundamental identities because they make solving equations simpler. Remember that the techniques we use for solving are not the same as those for verifying identities.
