Problem: Evaluate ( \int_1^2 (3x^2 + 2x) dx ).
Solution: First find the antiderivative: ( F(x) = x^3 + x^2 ). Then apply FTC: [ F(2) - F(1) = (8 + 4) - (1 + 1) = 12 - 2 = 10 ]
Final Answer: ( 10 )

The formula ( \int u , dv = uv - \int v , du ) is taught using the LIATE rule (Logarithmic, Inverse trigonometric, Algebraic, Trigonometric, Exponential) to choose ( u ). Zambak provides a "tabular integration" method for products of polynomials and exponentials, which saves immense time. Problem: Evaluate ( \int_1^2 (3x^2 + 2x) dx )
Sample Problem from Zambak: ( \int x^3 e^2x dx ). They solve it in 3 lines using a table of derivatives and integrals, rather than 10 lines of algebra.
