Question

$\int_{}^{}{\left( 1 + x + \frac{x^{3}}{\begin{matrix} 3 \end{matrix}} + \frac{x^{4}}{\begin{matrix} 4 \end{matrix}} + ..... \right)dx}$ equals to-

• A. e^x + c
• B. $\frac{1}{2}$e^x + c
• C. 2e^x + c
• D. None of these

Answer 1

Answer: (D)

None of these

Answer 2

=$\int_{}^{}{\left( e^{x} - \frac{x^{2}}{2} \right)dx}$ = e^x –$\frac{x^{3}}{6}$+ c
