∫ f(x) dx = F(x) + C
Symbolic anti-differentiation satisfying d/dx [F(x)] = f(x).
FREQUENTLY ASKED QUESTIONS (FAQ)
Why is '+ C' added to indefinite integrals?
Because the derivative of any constant is zero, there are infinitely many anti-derivatives that differ only by an additive constant. 'C' represents this arbitrary integration constant.
