Do you need to find the derivative of using limits?
Is this what you meant by your notation?
I'm finding this calculus problems interesting yet have trouble with a lot of them. hopefully this forum can help me
anyway....there is this derivative problem....
f(x)=x-2/x^2+1 Square root
f(x)=lim f(x-h) - f(x)/h
h>0
f(x)= lim x+h-2/(x+h)^2+1 Square root - x-2/x^2+1 Square root
h>0 /h
man, I hope that's understandable. hopefully someone can teach me how to do square roots and other stuff
just in case, the square roots go in x^2+1, (x+h)^2+1, and x^2+1 which are all denominators. and the h divides everything in the third part
anyway, I do have the answer.... 2x+1/(x^2+1)^3/2
I just don't know how to get there. I know the first step would be to cross multiply the ones in the 3rd part. I get lost after that
