Indefinite integral with constant of integration

The indefinite integral of a function f is an antiderivative F of f plus an arbitrary constant C, since differentiating removes any constant. It is used whenever an antiderivative is sought without fixed limits.

\int f(x)\,\mathrm{d}x = F(x) + C

What the symbols mean

the integrand, the function being integrated
an antiderivative of f(x), so that F'(x)=f(x)
arbitrary constant of integration
the variable of integration
