# NCERT solution class 11 chapter 3 Trigonometric Functions exercise 3.2 mathematics

## EXERCISE 3.2

#### Question 1:

Find the values of other five trigonometric functions if x lies in third quadrant.  Since x lies in the 3rd quadrant, the value of sin x will be negative.  #### Question 2:

Find the values of other five trigonometric functions if x lies in second quadrant.  Since x lies in the 2nd quadrant, the value of cos x will be negative #### Question 3:

Find the values of other five trigonometric functions if x lies in third quadrant.   Since lies in the 3rd quadrant, the value of sec x will be negative. #### Question 4:

Find the values of other five trigonometric functions if x lies in fourth quadrant.  Since x lies in the 4th quadrant, the value of sin x will be negative. #### Question 5:

Find the values of other five trigonometric functions if x lies in second quadrant.  Since x lies in the 2nd quadrant, the value of sec x will be negative.

∴sec x =  #### Question 6:

Find the value of the trigonometric function sin 765°

It is known that the values of sin repeat after an interval of 2π or 360°. #### Question 7:

Find the value of the trigonometric function cosec (–1410°)

It is known that the values of cosec repeat after an interval of 2π or 360°. #### Question 8:

Find the value of the trigonometric function It is known that the values of tan repeat after an interval of π or 180°. #### Question 9:

Find the value of the trigonometric function It is known that the values of sin repeat after an interval of 2π or 360°. #### Question 10:

Find the value of the trigonometric function
