1.Relation and Function
normal
Which pair $(s)$ of function $(s)$ is/are equal ?
where $\{x\}$ and $[x]$ denotes the fractional part $\&$ integral part functions.
A
$f(x) = cos(2tan ^{ -1} x) ; g(x) =$ $\frac{{1 - {x^2}}}{{1 + {x^2}}}$
B
$f(x) = \frac{{2x}}{{1 + {x^2}}} ; g(x) = sin(2cot ^{ -1} x)$
C
$f(x) ={e^{\ell n(\operatorname{sgn} {{\cot }^{ - 1}}x)}} ; g(x) ={e^{\ell n\left[ {1 + \left\{ x \right\}} \right]}}$
D
All of the above
Solution
Solution is Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
