Trigonometry

This chapter focuses on the measurement of angle and trigonometric ratios of angle and trigonometric identities. Essential information and formulas are given here. We will also learn to measure angles, trigonometric ratios, and relation between them.

This chapter covers trigonometric ratios of complementary angles. Necessary information and formulae are given for our understanding. We will also discuss trigonometric ratios of angle (90-theta) and solutions to different problems.

This chapter describes problems of height and distances. We will explore the concept of angle of elevation and angle of depression here. It also discusses the solution to real problems by the trigonometric method.
