Chapter Summary

The word ‘Trigonometry’ is acquired from the Greek words ‘trigon’ and ‘metron’. It signifies ‘estimating the sides of a triangle’. The subject was created to take care of geometric sums including triangles. It was read up by ocean chiefs for route, surveyor to outline the new lands, by designers and others. Currently, trigonometry is utilized in many regions like the study of seismology and planning electric circuits. Portraying the condition of an iota, foreseeing the levels of tides in the sea and analyzing a melodic tone are other regions.

In the earlier classes, you have concentrated on the trigonometric proportions of intense angles as the proportion of the sides of a right-angled triangle. In this part, the idea of trigonometric proportions to trigonometric functions has been explained. Thus, students will study their properties in a far-reaching way. In the first place, you will find out about radian measure – conversion, arc length, and finding the value of trigonometric functions. Next, Finding the value of trigonometric functions, given angle, (x + y) formula will be explained. Additionally, you will learn general arrangements, sine, cosine, and other trigonometry formulas in this part.
