Antidifferentiation

Finding a function from its derivative

Constant of integration cc

Arbitrary constant added to indefinite integrals

Symbol ∫\int

Integral sign

∫xr dx\int x^r \, dx where r≠−1r \neq -1

xr+1r+1+c\frac{x^{r+1}}{r+1} + c

Power rule restriction

Cannot use when r=−1r = -1 (division by zero)

∫kf(x) dx\int k f(x) \, dx

k∫f(x) dxk \int f(x) \, dx

∫[f(x)+g(x)] dx\int [f(x) + g(x)] \, dx

∫f(x) dx+∫g(x) dx\int f(x) \, dx + \int g(x) \, dx

dxdx in integral notation

Indicates integrating with respect to xx

Finding specific antiderivative

Use given condition to find value of cc

Power rule steps

Add 1 to power, divide by new power, add cc
