Solving Trigonometric Equations with Multiple Angles (I) | Lesson24

Trigonometric equations involving multiple angles can be challenging to solve, but there are specific techniques that can be used to simplify and solve them. In this type of equation, the trigonometric functions of multiple angles are involved, such as sin(2x), cos(3x), or tan(4x). To solve these equations, it is necessary to apply various identities and formulas to simplify them into a more manageable form, so that the solutions can be determined.

This process can involve using double angle, half angle, product-to-sum, and other trigonometric identities.
