ALGORITHMIC APPROACH IN TEACHING PUPILS OF SOLVING TRIGONOMETRIC EQUATIONS
Equations are considerable part of Mathematics as science and curriculum at school. Solving of trigonometric equations is not always simple because of objective and subjective reasons. From our point of view, teaching process how to solve trigonometric equations must be organized step-by-step: practice of solving simple trigonometric equations, then solving trigonometric equations of certain kind, and finally, in connections with accumulated knowledge of trigonometric expressions, solving equations of different types. Suggested article shows necessity of such coherence, reviews examples of trigonometric equations, and summarizes solving methods.
