Integration Rules
As with differentiation, we use a variety of rules when integrating functions. Below are a few of the most common.
The Constant Rule: ∫k dx = kx + C where k is a constant
The Power Rule: ∫ xn dx = + xn+1⁄n+1 + C when n ≠ 1
Exponential Rule: ∫ ekx dx = 1⁄kx ekx + C where k is a constant
Trigometric Rules:
∫ cos(x) dx = sin(x) + C
∫ sin(x) dx = -cos(x) + C
Sum/Difference Rules:
∫[f(x) + g(x)]dx = ∫f(x)dx + ∫g(x)dx
∫[f(x) - g(x)]dx = ∫f(x)dx - ∫g(x)dx
