A) \[a=2;\]\[b=1\]
B) \[a=2;\]\[b=0\]
C) \[a=3;\]\[b=-\,2\]
D) \[a=4;\]\[b=-1\]
Correct Answer: B
Solution :
\[l=\int\limits_{-1}^{1}{\frac{{{x}^{3}}}{{{x}^{2}}+2|x|+1}\,\,dx+\int\limits_{-1}^{1}{\frac{|x|+1}{{{(|x|+1)}^{2}}}dx}}\] \[\Rightarrow \] \[2\int\limits_{0}^{1}{\frac{dx}{1+x}}=2/n\,\,2\] [odd \[\Rightarrow \]vanishes even]You need to login to perform this action.
