SOME WAYS OF SOLVING TRIGONOMETRIC EQUATIONS IN SECONDARY SCHOOL

The scientific article discusses methods for solving trigonometric equations in the high school mathematics course. Trigonometric equations are one of the most important topics in high school mathematics. Among the concepts associated with trigonometry, the most important are trigonometric equations. When solving trigonometric equations, in addition to general concepts associated with equations, it is necessary to be able to use the properties and formulas of trigonometric functions. The school mathematics course uses the following basic trigonometric concepts: formulas for the relationship of trigonometric functions of an angle, formulas for addition, subtraction, double angles and half angles, formulas for converting sums and differences into product forms. Only by understanding the essence of the proof can you easily remember and consciously use them.
