$\int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} f(x) dx$ ની કિંમત શોધો,જ્યાં $f(x) = \sin |x| + \cos |x|$ અને $x \in [-\frac{\pi}{2}, \frac{\pi}{2}]$.

જો $\int_0^{2a} f(x) \, dx = 2 \int_0^a f(x) \, dx$ હોય,તો:

જો $f(t) = \int_0^t \tan^{(2n-1)} x \, dx$,$n \in N$,હોય,તો $f(t+\pi) =$

જો $\int_0^{10} f(x) d x=5$ હોય,તો $\sum_{k=1}^{10} \int_0^1 f(k-1+x) d x=$

ધારો કે $f$ એ $[0,1]$ પર વ્યાખ્યાયિત એક સતત વિધેય છે જેથી $\int_0^1 f^2(x) dx = (\int_0^1 f(x) dx)^2$ થાય. તો,$f$ નો વિસ્તાર
