$\int \frac{\sec x \cdot \tan x}{9-16 \tan ^2 x} \,d x$ નું મૂલ્ય કેટલું થાય?

  • A
    $\frac{1}{24} \log \left(\frac{5+4 \sec x}{5-4 \sec x}\right)+c$,(જ્યાં $c$ એ સંકલનનો અચળાંક છે)
  • B
    $\frac{1}{40} \log \left(\frac{5+4 \sec x}{5-4 \sec x}\right)+c$,(જ્યાં $c$ એ સંકલનનો અચળાંક છે)
  • C
    $\frac{1}{24} \log \left(\frac{5-4 \sec x}{5+4 \sec x}\right)+c$,(જ્યાં $c$ એ સંકલનનો અચળાંક છે)
  • D
    $\frac{1}{40} \log \left(\frac{5-4 \sec x}{5+4 \sec x}\right)+c$,(જ્યાં $c$ એ સંકલનનો અચળાંક છે)
