Integrals are a fundamental concept in calculus, used to calculate areas under curves and solve complex mathematical problems. This guide covers indefinite integrals, definite integrals, and various integration techniques.
Key points:
• Indefinite integrals are written as ∫f(x)dx = F(x) + C
• The fundamental theorem of calculus connects derivatives and integrals
• Integration techniques include substitution, parts, and partial fractions
• Riemann integrals are used to calculate definite integrals and areas
