You don't need to break up the integral. You can start from the first term $\frac{d}{dx} \int_{\sin(x)}^{x^2} t^3 \tan(t) dt$ . Leibniz's rule gives a direct formula for this derivative.
20 Απρ 2016 · Integral with Functions as Bounds. One Bound. $$\text{Calculate } \frac{d}{dx} \int_{a}^{h(x)}{f(t)}\, \mathrm{d}t$$ $$\text{Let } G(x) = \int_{a}^{x}{f(t)}\, \mathrm{d}t$$ $$G(h(x)) = \int_{a}^{h(x)}{f(t)}\, \mathrm{d}t$$ $$\frac{d}{dx}G(h(x)) = G'(h(x))h'(x)$$ $$=f(h(x))h'(x)$$ . Two Bounds.
Therefore, variable bounds only happen on the inside integrals. If \(g\) and \(h\) are function, I have two general forms for integration of two-variable scalar fields. \begin{align*} \amp \int_a^b \int_{g(x)}^{h(x)} f(x,y) dy dx\\ \amp \int_a^b \int_{g(y)}^{h(y)} f(x,y) dx dy \end{align*}

Compute the definite integral \(\displaystyle\int_0^{2\pi} x \sin (x) \, dx\text{.}\) We start with the indefinite integral, which we compute by parts. Based on what happened with \(x e^x\text{,}\) let's decide to start with the choice \(u = x, v' = \sin x\text{.}\) Then \(v = - \cos x\) and \(u' = 1\text{,}\) which yields
