## NCERT Solutions Class 10 Maths Chapter 8 Exercise 8.1 Tips

NCERT solutions class 10 maths chapter 8 exercise 8.1 is all about identifying and applying the right formula, hence a formula chart can be helpful for students. Students should learn how to analyze a question and link it to the right formula. This can be done easily by exploring the derivation of these formulas and remembering the value of sin, cos, and tan with respect to a right-angled triangle.

Some of the other formulas used in the NCERT solutions class 10 maths chapter 8 exercise 8.1 Introduction to Trigonometry are:

- cosec A = 1/ sin A = Hypotenuse / Perpendicular
- sec A = 1/ cos A = Hypotenuse / Base
- cot A = 1/ tan A = Base / Perpendicular

As it can be observed these three ratios are just reciprocals of the 3 other main trigonometric ratios.
