About the Chapter – Introduction to Trigonometry

Trigonometry is a Mathematics concept that focuses on triangles. Trigonometry is a blend of ‘trigono’ and ‘metry’, which means triangle and measure. 

The chapter includes proper methods and formulae to help the students find the missing sides and angle of a triangle.  Class 10 chapter 8 has been segmented into five sections. 

The first section presents the problems depicted using the right-angle triangle and the second section comprises an introduction to trigonometric ratios with examples. The students can work on the exercises to understand the topics in detail. The segment also explains the derivation of sine, cosine, and several other trigonometric functions.

The third section talks about the trigonometric ratios of measurement. The fourth section presents a few solved examples, trigonometric ratio criteria for the complementary angles and the exercises. The last section explains the subject associated with the trigonometric identities, accompanied by examples and exercises.

Question: State whether the following condition is true or false: The value of sinθ increases as θ increases between 0 and 90 degrees.

Solution: We know the values of sine for different values of θ between 0 and 90 degrees

sin 0 = 0

sin 30 = 1/2 = 0.5

sin 45 = 1/√2 = 0.7071

sin 60 = √3/2 = 0.866

sin 90 = 1

It can be seen that the value of sinθ increases as θ increases between 0 and 90 degrees. Therefore, the given statement is true.
