Primary objective of this assignment is to Define and Discuss on Trigonometric Equations. Here explain Trigonometric Equations with proper examples. Trigonometric identities are true for all those replacement values for the variables for which both sides of the particular equation are defined. Conditional trigonometric equations usually are true for only several replacement values. Solutions in a very specific interval, such seeing that 0 ≤ x ≤ 2π, are generally called primary solutions. Holistic solution is a method that names all doable solutions.
