A) \[\frac{1}{2}\ell n\,\,(1+\sqrt{1+{{x}^{2}})}+c\]
B) \[2\sqrt{1+\sqrt{1+{{x}^{2}}}}+c\]
C) \[2\,\,(1+\sqrt{1+{{x}^{2}}})+c\]
D) None of these
Correct Answer: B
Solution :
\[\frac{x}{\sqrt{(1+{{x}^{2}})\left( 1+\sqrt{1+{{x}^{2}}} \right)}};\] put \[1+\sqrt{1+{{x}^{2}}}={{t}^{2}}]\]You need to login to perform this action.
