Find the slope of the tangent line to the curve f(x)=x-x^3 at the point (1,0)
So, I went through and plugged (a+h) in everywhere I saw "x"
(a+h)-(a+h)^3
Factoring:
(a+h-a^3-3a^2h-3ah^2-h^3)
I'm really stuck on what to do next...I don't see anything you can cancel/pull out? I know you need to cancel the h in the denominator, but I can't pull an h out because of the "a"s...
Thank you!
