Answer & Solution

Correct Answer

(D) \(\frac{x}{2} \sqrt{a^2+x^2}-\frac{a^2}{2} \operatorname{Sinh}^{-1} \frac{x}{a}\)

Step-by-step Solution

Detailed explanation

\( \int_0^{\mathrm{x}} \frac{\mathrm{t}^2}{\sqrt{\mathrm{a}^2+\mathrm{t}^2}} \mathrm{dt} = \int_0^{\mathrm{x}} \frac{\mathrm{t}^2+\mathrm{a}^2-\mathrm{a}^2}{\sqrt{\mathrm{a}^2+\mathrm{t}^2}} \mathrm{dt} \)…
