$\int \frac{dx}{x(x^2+1)^3} = ?$

  • A
    $\frac{1}{2(x^2+1)} + \frac{1}{4(x^2+1)^2} + \log \sqrt{\frac{x^2}{x^2+1}} + c$
  • B
    $\frac{1}{x^2+1} + \frac{1}{2(x^2+1)^2} + \log \sqrt{\frac{x}{x^2+1}} + c$
  • C
    $\frac{1}{2(x^2+1)} + \frac{1}{4(x^2+1)^3} + \log \sqrt{\frac{x}{x+1}} + c$
  • D
    $\frac{2}{x^2+1} - \frac{1}{4(x^2+1)^2} - \log \sqrt{\frac{x}{x+1}} + c$

જો $\int \frac{3x+1}{(x-1)^3(x+1)} dx = A \cdot \log \left|\frac{x+1}{x-1}\right| + \frac{B}{x-1} + \frac{C}{(x-1)^2} + D$ હોય,તો $A+B+C=$

$ \int \frac{x^2+1}{x(x^2-1)} dx $

ધારો કે $f(x) = \int \frac{16x + 24}{x^2 + 2x - 15} dx$. જો $f(4) = 14 \log_e(3)$ અને $f(7) = \log_e(2^\alpha \cdot 3^\beta)$, જ્યાં $\alpha, \beta \in N$, તો $\alpha + \beta$ ની કિંમત શોધો:
