Description

8 problems: (1-2) Euler with h=0.1: solve dy/dx=x+y, y(0)=1 for 3 steps. Solve dy/dx=-2y, y(0)=3 for 4 steps. (3) 'Compare Euler result to exact for dy/dx=y, y(0)=1 at x=1 with h=0.1 vs h=0.01.' (4-5) Improved Euler: same ODE, 2 steps. Compare accuracy to Euler. (6) RK4: compute one step with h=0.1
