Antiderivatives:Antiderivatives are functions that "undo" derivatives. They represent families of functions that have the same derivative.
Riemann Sums: Riemann sums are approximations of definite integrals by dividing an interval into smaller subintervals and summing up areas using rectangles or trapezoids.
Fundamental Theorem of Calculus:The fundamental theorem of calculus establishes a connection between definite integrals and antiderivatives, stating that if F(x) is an antiderivative of f(x), then ∫[a,b] f(x) dx = F(b) - F(a).
