ddx∫x2x3 1log⁡tdt is equal to - Infinity Learn by Sri Chaitanya

A
$\frac{1}{\log x}$
B
$\frac{x^{2}}{\log x}$
C
$\frac{x^{2} - x}{\log x}$
D
None of these

Solution:

$\begin{array}{l} \frac{d}{dx} (\int_{x^{2}}^{x^{3}} \frac{1}{\log t} \cdot dt) = \frac{1}{\log x^{3}} \cdot \frac{d}{dx} (x)^{3} - \frac{1}{\log x^{2}} \cdot \frac{d}{dx} (x^{2}) \\ = \frac{3 x^{2}}{3 \log x} - \frac{2 x}{2 \log x} \\ \Rightarrow \frac{d}{dx} (\int_{x^{2}}^{x^{3}} \frac{1}{\log t} dt) = \frac{1}{\log x} \cdot (x^{2} - x) \end{array}$
