$\int_{-1}^{0} \frac{dx}{x^2 + 2x + 2} = $

$\int_{-1}^{1} [x + [x + [x]]] \, dx = $ (જ્યાં $[\cdot]$ એ મહત્તમ પૂર્ણાંક વિધેય દર્શાવે છે)

જો $2f(x) - 3f\left( \frac{1}{x} \right) = x$ હોય,તો $\int_1^2 f(x) \, dx$ ની કિંમત શોધો.

$\int_{1/4}^{1/2} \frac{dx}{\sqrt{x - x^2}} = $

ધારો કે $f(x) = 2 + |x| - |x - 1| + |x + 1|$,$x \in R$. ધ્યાનમાં લો:
$(S1): f^{\prime}\left(-\frac{3}{2}\right) + f^{\prime}\left(-\frac{1}{2}\right) + f^{\prime}\left(\frac{1}{2}\right) + f^{\prime}\left(\frac{3}{2}\right) = 4$
$(S2): \int_{-2}^{2} f(x) dx = 12$
