The value of ( ⁻¹ x ) is
Options
- A1 1+x^2
- B1+x^2
- C1 x 1+x^2
- Dx 1+x^2
Correct answer
A. 1 1+x^2
Step-by-step solution
array ll & ( ⁻¹ x ) & Let ⁻¹ x= t & x= t & 1+ ^2 t =1+x^2 & cosec ^2 t =1+x^2 & cosec t = 1+x^2 & t = 1 1+x^2 & t = ⁻¹ ( 1 1+x^2 ) & ( ⁻¹ x )= ( ⁻¹ ( 1 1+x^2 ) ) & = 1 1+x^2 array
