જો $I=\int \frac{\sin x+\sin ^3 x}{\cos 2 x} \,d x=P \cos x+Q \log \left|\frac{\sqrt{2} \cos x-1}{\sqrt{2} \cos x+1}\right|+c,$ (જ્યાં $c$ એ સંકલનનો અચળાંક છે),તો $P$ અને $Q$ ની કિંમતો અનુક્રમે શું થાય?

  • A
    $\frac{1}{2}, \frac{3}{4 \sqrt{2}}$
  • B
    $\frac{1}{2}, \frac{-3}{4 \sqrt{2}}$
  • C
    $\frac{1}{2}, \frac{3}{2 \sqrt{2}}$
  • D
    $\frac{1}{2}, \frac{-3}{2 \sqrt{2}}$

$\int \frac{x + \sin x}{1 + \cos x} dx =$

જો $I(x) = \int e^{\sin^2 x} (\cos x \sin 2x - \sin x) dx$ અને $I(0) = 1$ હોય,તો $I\left(\frac{\pi}{3}\right)$ ની કિંમત શોધો.

જો $\int \frac{1 - (\cot x)^{2021}}{\tan x + (\cot x)^{2022}} dx = \frac{1}{A} \log |(\sin x)^{2023} + (\cos x)^{2023}| + c$ હોય,તો $A = . . . . . .$
