Description

8 problems: (1-2) Trapezoid rule with n=4: ∫₀² x²dx (compare to exact=8/3), ∫₀¹ eˣdx. (3-4) Simpson's rule with n=4: same integrals. Compare errors. (5) 'Approximate ∫₀¹ e^(-x²)dx using trapezoid with n=4.' (No closed form!). (6) 'How many trapezoid intervals needed for error < 0.0001 on [0,1] if ma
