$\int \frac{(3 x-2) \tan \left(\sqrt{9 x^2-12 x+1}\right)}{\sqrt{9 x^2-12 x+1}} d x=$

$\begin{aligned} & \int \frac{dx}{(2 \sin x+\sec x)^4}=A(1+\tan x)^{-5} \\ & +B(1+\tan x)^{-6}+C(1+\tan x)^{-7}+k, \text{ તો } \\ & A+B+C= \end{aligned}$

જો $\int \frac{d x}{\sqrt{\sin ^3 x \cos x}}=g(x)+c$ હોય,તો $g(x)$ ની કિંમત શોધો.

ધારો કે $n \geq 2$ માટે $f(x) = \frac{x}{(1+x^n)^{1/n}}$ અને $g(x) = \underbrace{(f \circ f \circ \ldots \circ f)}_{n \text{ વખત }}(x)$ છે. તો $\int x^{n-2} g(x) \, dx$ ની કિંમત શોધો.

$\int \frac{d x}{\sqrt{x}(x+9)}$ ની કિંમત શોધો.
