$\int_{x}^{x^{2}} e^{t^{2}} d t$

Step 1

This derivative could not be completed using the chain rule. Mathway will use another method.

Step 2

Split the integral into two integrals where $c$ is some value between $x$ and $x^{2}$ .

$\frac{d}{d x} [\int_{x}^{c} e^{t^{2}} d t + \int_{c}^{x^{2}} e^{t^{2}} d t]$

Step 3

By the Sum Rule, the derivative of $\int_{x}^{c} e^{t^{2}} d t + \int_{c}^{x^{2}} e^{t^{2}} d t$ with respect to $x$ is $\frac{d}{d x} [\int_{x}^{c} e^{t^{2}} d t] + \frac{d}{d x} [\int_{c}^{x^{2}} e^{t^{2}} d t]$ .

$\frac{d}{d x} [\int_{x}^{c} e^{t^{2}} d t] + \frac{d}{d x} [\int_{c}^{x^{2}} e^{t^{2}} d t]$

Step 4

Swap the bounds of integration.

$\frac{d}{d x} [- \int_{c}^{x} e^{t^{2}} d t] + \frac{d}{d x} [\int_{c}^{x^{2}} e^{t^{2}} d t]$

Step 5

Take the derivative of $- \int_{c}^{x} e^{t^{2}} d t$ with respect to $x$ using Fundamental Theorem of Calculus.

$- e^{x^{2}} + \frac{d}{d x} [\int_{c}^{x^{2}} e^{t^{2}} d t]$

Step 6

Take the derivative of $\int_{c}^{x^{2}} e^{t^{2}} d t$ with respect to $x$ using Fundamental Theorem of Calculus and the chain rule.

$- e^{x^{2}} + \frac{d}{d x} [x^{2}] e^{{(x^{2})}^{2}}$
