Lesson#2 Solution of a Trigonometric Equation and its types What is Solution of a Trigonometric Equation ? Solution of a Trigonometric Equation: The value of the unknown variable which satisfies the trigonometric equation is called solution of trigonometric equation. So the trigonometric equations have infinite number of solutions due to the periodic behavior of trigonometric functions. There are two types of solutions of trigonometric equations; 1) Principal Solutions: Solutions of a trigonometric equation for which 0°≤θ Solutions of Trigonometric Equations Chapter No 14 Exercise No 14 Mathematics part 1
