WebThe power rule tells us how to find the derivative of any expression in the form x^n xn: \dfrac {d} {dx} [x^n]=n\cdot x^ {n-1} dxd [xn] = n ⋅ xn−1. The AP Calculus course doesn't require knowing the proof of this rule, but we believe that as long as a proof is accessible, there's … Webe x = ∑ k = 0 ∞ x k k!, then it will follow fairly readily that is its own derivative, using Taylor series properties. If on the other hand you've defined e x = lim n → ∞ ( 1 + x n) n, then you may have a slightly harder way to go. I think using the difference of th powers formula may help.

WebNov 22, 2024 · The epsilon-delta definition says a function is differentiable if, for every ϵ > 0, there exists a δ > 0 such that x − x0 < δ implies f ( x) − f ( x0) x − x0 − f ′ (x0) < ϵ. Thus, I need to find a delta, as function of epsilon, and possibly x0, such that whenever the first inequality is true the second one is as well.
