Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to find angle measures given interval and function values.

Students will be able to

solve simple trigonometric equations by applying invoice operations, simple algebraic methods, or simple trigonometric identities,
recognize and use the periodicity of trigonometric functions to identify all of the solutions to a trigonometric equation in a specified range or identify the general solution (this includes using the graphs of trigonometric functions to identify solutions),
solve equations involving the reciprocal trigonometric functions (secant, cosecant, and cotangent).
