Question

solve and simplify

Answer 1

\[\tan ^{-1}\left(\ \frac{ 1 }{ \sqrt{x^2+1} }\right)\]
wat shud we solve

Answer 2

simplify it

Answer 3

not clear ıs thıs equal to somethıng

Answer 4

no
can we put x= tan theta

Answer 5

yes, put x=tan y

Answer 6

but at the end , i got theta
which is equal to tan^-1x

Answer 7

so this is the answer

Answer 8

I am too lazy to check if you'll get theta in the end or not, but if you are getting theta, then yes, tan^-1 x is your final ans

Answer 9

okay
thank u @shubhamsrg

Answer 10

glad to help

Answer 11

no, i m getting tan^-1(costheta)

Answer 12

convert tan^-1 into cos^-1 by using trigonometric manipulations

Answer 13

hmm, how

Answer 14

tan^-1 z = t
z = tant
z^2 = sec^2 t -1
cost = sqrt(1/ 1+z^2)
t= cos^-1 (sqrt( 1/ 1+z^2) )
