The derivative of the upper limit $u=\sqrt{t}$ with respect to $t$ is $1/(2\sqrt{t})$. This factor is used in the chain rule when differentiating an integral with this variable upper limit.

Conditions: $t > 0$.; The upper limit is defined as $u=\sqrt{t}$.

The derivative of the upper limit $u=\sqrt{t}$ with respect to $t$ is $1/(2\sqrt{t})$. This factor is used in the chain rule when differentiating an integral with this variable upper limit.

Conditions: $t > 0$.; The upper limit is defined as $u=\sqrt{t}$.

The simplified derivative is $\sin(t^{5/2})/(2t^{5/2})$. This is obtained by evaluating the integrand at $x=\sqrt{t}$ and multiplying by the derivative of the upper limit, $1/(2\sqrt{t})$.

Conditions: The integrand is $\sin(x^5)/x^4$.; The lower limit is the constant 2.; The upper limit is $\sqrt{t}$.; $t > 0$.

The factor is essential because the Fundamental Theorem of Calculus combined with the Chain Rule requires multiplying the integrand evaluated at the upper limit by the derivative of that limit. Without this factor, the rate of change of the accumulated area with respect to the outer variable $t$ would be incorrect.

Conditions: The upper limit is a function of $t$, not just $t$ itself.; The integrand is continuous.

The net-change formula states that for a continuously differentiable function on an interval, integrating its derivative gives the endpoint difference. Specifically, the integral of the derivative $f'$ from $a$ to $b$ equals $f(b) - f(a)$.

Conditions: The function is continuously differentiable on the interval.; The integration is over the interval from $a$ to $b$.

This occurs when the integrand is continuous on the relevant interval. Under this condition, the Fundamental Theorem of Calculus states that the derivative of the integral with respect to its upper limit is the integrand evaluated at that limit.
