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 $\sqrt{t}$.; $t > 0$.
