differentiate with respect to x:Question is:(a)power 2+(x)power2/{[(a)power2-(x)power2}sq.root]}?

Answer 1

a^2+x^2
----------
(a^2-x^2)^2



~>

(a^2+x^2)
---------------------
(a^2-x^2)(a^2+x^2)

Cancel the (a^2+x^2)


~>
=1/(a^2-x^2)



uhmm im not really sure of that.

Answer 2

practice, baby practice. u need lot more practice in differential calculus.
im not gonna post the solution as it'll be 2oo long but u can differentiate it by using the quotient rule.
if u don't know it, search on google or yahoo.

Answer 3

if it is
y=(2+x^2)/sqrt(a^2-x^2)
then
y'={ 2xsqrt(a^2-x^2)+[x(2+x^2)]/sqrt(a^2-x^2)}/(a^2-x^2)
