What to Focus On
- Integration is the reverse of differentiation
- ∫f(x)dx represents the antiderivative of f(x)
- C is the constant of integration (arbitrary constant)
- ∫xⁿ dx = xⁿ⁺¹/(n+1) + C (n ≠ -1)
- ∫1/x dx = log|x| + C
- ∫eˣ dx = eˣ + C
- Used for integrals of the form ∫f(g(x))·g'(x)dx
- Choose substitution to simplify the integrand
- Replace both the function and differential
Common Mistakes to Avoid
When integrating by substitution, students forget to change the limits of definite integrals
Students believe ∫ f(x)g(x) dx = ∫ f(x) dx × ∫ g(x) dx
Students think the constant of integration C is the same for all integrals and can be ignored in definite integrals
