WebNov 29, 2024 · Explanation: Using the limit definition of the derivative: f '(x) = lim h→0 f (x + h) − f (x) h. With f (x) = x3 we have: f '(x) = lim h→0 (x +h)3 − x3 h. And expanding using the binomial theorem (or Pascal's triangle) we get: f '(x) = lim h→0 (x3 +3x2h + 3xh2 + h3) −x3 h. = lim h→0 3x2h + 3xh2 +h3 h. = lim h→0 3x2 +3xh +h2.
