What are even and odd trigonometric functions

The video tutorial explains the concepts of even and odd functions, both graphically and algebraically. It uses examples like X^2 and X^3 to illustrate these concepts. The tutorial also covers the properties of trigonometric functions, identifying which are even (cosine and secant) and which are odd (sine, cosecant, tangent, and cotangent). Understanding these properties is crucial for solving problems involving negative values in trigonometric functions.
