This material is a mathematical material for class XI high school level. Formula Material The number of differences in two trigonometric angles is an advanced material from trigonometry that has been discussed earlier in class X. Prerequisite material that must be mastered is the value of special trigonometric comparisons, trigonometric comparison values in four quadrants, trigonometric identity.
Come on, read the article to add knowledge.

The Trigonometry Formula for Double Angles is a continuation of the Sum and Difference of Trigonometry Angles Formula

This time we will discuss the formula for the sum and difference of two angles in trigonometry along with evidence and example questions

determining the trigonometric ratio values of special angles 0°, 30°, 45°, 60°, 90° and solving them in everyday life

Trigonometry is closely related to triangles. There are several types of Trigonometric Comparisons in Right Triangles, namely sin, cos, tan.
