Class 11th Maths – RD Sharma Chapter 5 : trigonometric Functions Exercise 5.2 Solutions

1. Find the values of the other five trigonometric functions in each of the following:

       (i) cot x = 12/5 , x in quadrant III Watch Solution

       (ii) cos x = −1/2 , x in quadrant II Watch Solution

      (iii) tan x = 3/4 , x in quadrant III Watch Solution

      (iv) sin x = 3/5 , x in quadrant I Watch Solution

2. If sin x = 12/13 and x lies in the second quadrant, find the value of sec x + tan x.  Watch Solution
3. If sin x = 3/5 , tan y = 1/2 and π/2 < x < π < y < 3π/2 , find the value of 8 tan x − √5 sec y. Watch Solution
4. If sin x + cos x = 0 and x lies in the fourth quadrant, find sin x and cos x. Watch Solution
5. If cos x = −3/5 and π < x < 3π/2 , find the values of other five trigonometric functions and hence evaluate (cosec x + cot x) / (sec x − tan x). Watch Solution
