Challenge Problems
Push your limits with challenges.
Question 1
Consider the ODE \( \frac{dy}{dt} = y^2 \) with \( y(0) = 1 \) and \( h = 0.1 \). Compute the first three approximations using RK4.
💡 Hint: Start with each slope and ensure you use the previous slopes to make adjustments.
Question 2
Discuss the effects of varying the step size \( h \) on the accuracy of RK4. What might happen if you make \( h \) too large?
💡 Hint: Consider how the step size impacts the function sampling.
