CBSE NCERT Solutions for Class 11 Maths Chapter 3: Points to Remember
In earlier classes, students would have studied the trigonometric ratios of acute angles as the ratio of the sides of a right-angled triangle. In this chapter, the concept of trigonometric ratios to trigonometric functions has been explained. Hence, students will study their properties in a comprehensive way. Additionally, they will learn general solutions, sine, cosine, and other trigonometry formulas in this chapter.
We have provided a summary of the important points in Mathematics Chapter 3 of Class 11 below. Therefore, students can refer to them for revision.
- If in a circle of radius r, an arc of length l subtends an angle of θ radians, then l = r θ
Radian measure = π/180× Degree measure
Degree measure =180/π× Radian measure - If none of the angles x, y and (x ± y) is an odd multiple of π/ 2, then tan (x + y) = (tan x+tan y)/(1-tan x tan y)
- If none of the angles x, y and (x ± y) is a multiple of π, then cot (x + y) = (cot x cot y-1)/(cot y +cot x)
