ધારો કે $[\cdot]$ એ મહત્તમ પૂર્ણાંક વિધેય દર્શાવે છે. તો $\int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} \left( \frac{12(3+[x])}{3+[\sin x]+[\cos x]} \right) dx$ ની કિંમત શોધો:

$\int_{-\pi / 4}^{\pi / 4} x^3 \sin ^4(x) d x=$

જો $\int_0^\pi {x\,f({{\cos }^2}x + {{\tan }^4}x)\,dx} = k\int_0^{\pi /2} {f({{\cos }^2}x + {{\tan }^4}x)\,dx,}$ હોય,તો $k$ ની કિંમત શોધો.

$\int_{0}^{\pi} \frac{e^{\cos x}}{e^{\cos x}+e^{-\cos x}} d x=$

$\frac{\int_{0}^{\pi/2} (x \cos x + 1) e^{\sin x} dx}{\int_{0}^{\pi/2} (x \sin x + 1) e^{\cos x} dx}$ નું નિરપેક્ષ મૂલ્ય - ની બરાબર છે.
