Using the differential equation dy/dx = x^2 - y with the initial condition y(0) = 0 and step size h = 0.1, compute the value of y at x = 0.1 using RK2.
💡 Hint: Remember to compute at both start and midpoint.
Solve the initial value problem dy/dx = ln(x + 1) - y with y(0) = 1 and h = 0.1. Find y(0.1) using RK2.
💡 Hint: Focus on the computation of k1 and k2 carefully.
