A) \[\frac{1}{2}/n\,(1+\sqrt{1+{{x}^{2}}})+c\]
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 :
\[\frac{x}{\sqrt{(1+{{x}^{2}})\,\,(1+\sqrt{1+{{x}^{2}}})}};\] put \[\sqrt{1++{{x}^{2}}}={{t}^{2}}\]You need to login to perform this action.
