ધારો કે $f:(0, \infty) \rightarrow \mathbb{R}$ અને $F(x)=\int_0^x t f(t) d t$. જો $F(x^2)=x^4+x^5$ હોય,તો $\sum_{r=1}^{12} f(r^2)$ ની કિંમત શોધો:

$\int_0^a \frac{x \, dx}{\sqrt{a^2 + x^2}} = $

જો $\int_a^b x^3 dx = 0$ અને $\int_a^b x^2 dx = \frac{2}{3}$ હોય,તો

$\int_0^2 \frac{x^3}{(x^2 + 1)^{3/2}} \, dx = $
