can brainly solve it? I don't need answer.. explain it...

Answer 1

It depend upon the users of brainly how they answer to this question....!
I think that brainly can solve it

Answer 2

Given: tan^-1 x + cot^- 1 x

Let A = tan^-1 x.

x = tan A

Now,

A + cot^-1 x

A + cot^-1(tan A)

$A + cot^{-1}(cot( \frac{ \pi }{2} - A))$

We know that cot^-1(cot x) = x

$A + \frac{ \pi }{2} - A$

$\frac{ \pi }{2}$


Hope this helps!
