\int {\frac{{dx}}{{x\sqrt {{x^4} - 1} }}}

is equal to

View answer and explanation

Correct option: B

\frac{1}{2}{\sec ^{ - 1}}{x^2} + c

Option D (

\sin x

) is correct because if

f(x) = \sin x

, then

\int f(x) \cos x dx = \int \sin x \cos x dx = \frac{1}{2} \sin^2 x + c = \frac{1}{2} f^2(x) + c

.
