Points to Remember
To help guide students in their exam preparations for NCERT Class 10 Maths Chapter 8 Introduction to Trigonometry, we have provided some of the important points to remember below:
Trigonometric Ratios:
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
cosec θ = Hypotenuse/Perpendicular
sec θ = Hypotenuse/Base
cot θ = Base/Perpendicular
Reciprocal Relationship of Trigonometric Ratios:
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Ratio Identity:
tan θ = sin θ/cos θ
cot θ = cos θ/sin θ

Topics and Sub-topics
The word trigonometry comes from the Greek words tri (meaning three), gon (meaning side), and metron (meaning measure). Trigonometry is the science of the relationship between the sides and angles of a triangle. Most of the technologically advanced methods used in engineering and physical sciences today are based on trigonometry concepts. This branch of mathematics, called trigonometry, is very useful when dealing with heights and distances that are not easy to measure.
