What You'll Learn
Apply the Midpoint Rule to approximate definite integrals using rectangle midpoints
Use the Trapezoid Rule to estimate area under curves with trapezoidal shapes
Calculate integrals with Simpson's Rule for maximum accuracy using parabolic approximations
Determine error bounds for each numerical method using standard error formulas
Identify when numerical integration is necessary for functions that cannot be integrated analytically
What You'll Practice
1
Approximating integrals using Midpoint Rule with specified subintervals
2
Computing area estimates with Trapezoid Rule for various functions
