Rules for Differentiating Functions Weeks 7 & 8
1. General Power Rule: If u(x) is a differentiable function and n is any real number
and y = f(x) = [u(x)]n, then dy/dx = n[u(x)]n-1 u(x), or dun/dx = nun-1 du/dx, where u =
u(x) (p. 235).

Rules for Differentiating Functions Weeks 5 & 6
1. Four-step process for differentiating functions using limits (p. 172).
2. Constant Function Rule: If y = f(x) = k, then dy/dx = 0 (p. 179).
3. Power Function Rule: If y = xp, then dy/dx = pxp-1
