if y=(xcos^-1x/√1-x^2)-log√1-x^2
then find dy/dx
pls answer this question experts!!!

@ aisha plz take a pic of question . As I am not able to understand it well. Problem of integrals may not be solvable if I note down question wrongly.

Or plz confirm that your question is xcos​-1x/(1-x2)1/2  - log(1-x2)1/2

the answer is cos^-1 x/(1-x^2)^3/2

rather using product rule use quotient rule for differentiating
u urself will get the answer there is just a slight mistake

oh sorry
I got dat

hey @aisha
just put x=cos z 
you will get z*tan(z)-log(sinz)
​now differentiate to get the ans...
