**(2) **

**(3) **

**(4) **

**(5) **

**(6) **

**(7) **

**(8)**

**(9) **

**(10) **

**Solution:**

(1) Let = y

∴

the range of principal value of sin^{-1} is

**Ex 2.1 Class 12 Maths Question 11-12.**

**Find the principal values of the following:**

**(11) **

**(12) **

**Solution:**

(11)

Now tan^{-1} (1) =

∴the range of principal value branch of

**Ex 2.1 Class 12 Maths Question 13.**

**If sin ^{-1} x = y, then**

**(a) 0 ≤ y ≤ π**

**(b)**

**(c) 0 < y < π**

**(d)**

**Solution:**

The range of principal value of sin is

∴ if sin

^{-1}x = y then

Option (b) is correct

**Ex 2.1 Class 12 Maths Question 14.**

** is equal to**

**(a) π**

**(b) **

**(c) **

**(d) **

**Solution:**

∴ Principal values of sec^{-1} is [0,π] –

Option (b) is correct
