QUESTION: 1

### Evaluate ​

Solution:  QUESTION: 2

### Value of Solution:

Since sin-1(-π/2)=-sin-1(π/2)=-1

so, cot -1(-1)

let (- cot-11)=α

cot α =-1 =cot (π/2+π/4) =3π/4

QUESTION: 3

### The value of is given by​

Solution:   QUESTION: 4

The principal value of tan-1 (-1) is given by​

Solution: QUESTION: 5

if 5 sin θ = 3, then is equal to

Solution:

sin θ is 3/5.
on simplifying:
(secθ + tanθ)/(secθ - tanθ)
We get, (1+sin θ)/(1-sin θ)
=(1+3/5)/(1-3/5)
=(8/2)
