h ⁻¹ ( x 1-x^2 ) is equal to
Options
- Acoth ⁻¹ x
- Bh⁻¹ x
- C- ⁻¹ x
- Dh ⁻¹ x
Correct answer
D. h ⁻¹ x
Step-by-step solution
We have, aligned & h ⁻¹ ( x 1-x^2 )= & x 1-x^2 = aligned aligned & Now, ^2 =1+ ^2 & =1+ x^2 1-x^2 = 1 1-x^2 & = 1 1-x^2 & h = h =x & = h ⁻¹ x & h ⁻¹ ( x 1-x^2 )= ⁻¹ x & aligned
