ધારો કે $f(x) = x$, $f_1(x) = f(\log x)$, $f_2(x) = f_1(\log x)$, $f_3(x) = f_2(\log x) \dots$ વગેરે. તો $\int \frac{1}{f(x) f_1(x) f_2(x) \dots f_{2026}(x)} dx = \dots$

$k \in N, \int \frac{1-k \cos ^2 x}{\sin ^k x \cdot \cos ^2 x} d x=$

$\int \sec x \tan^3 x \, dx = $

જો $\int \frac{a \cos x-2 \sin x}{b \sin x+5 \cos x} d x=\frac{7}{41} x+\frac{22}{41} \log |b \sin x+5 \cos x|+C, (a>0, b>0)$, તો $\int \frac{d x}{b+a \cos x}=$

જો $f(x) = \int \left[ \tan^2 x + \cot^2 x + \frac{4(\sin^3 x + \cos^3 x)}{\sin^2 2x} \right] dx$ અને $f\left(\frac{\pi}{4}\right) = 0$ હોય, તો $3 \left[ f\left(\frac{\pi}{6}\right) + 2 \right] = $
