Question

$\int xdx$ is integral of x wrt x $

• A. $I=\frac{x^2}{3}+C$
• B. $I=\frac{x^3}{2}+C$
• C. $I=\frac{x}{2}+C$
• D. $I=\frac{x^2}{2}+C$

Answer 1

The correct option is D $I=\frac{x^2}{2}+C$

Given,

$I=\int xdx$

Formula used:

$\int x^{n}dx=\frac{x^{n+1}}{n+1}+C$

Apply the formula, we get

$I=\frac{x^{1+1}}{1+1}+C$

$I=\frac{x^2}{2}+C$

Hence, this is the answer.
