Can you help figure out how to set up excel to solve this, or a way to calculate it by hand?
Calculate the first 3 terms of the RK-2 (improved euler) solution of the differential equation:
y' = y - x when y(1) = 1
n = 0, Xn = 1, Yn = 1, Yn+1 = ?
n = 1, Xn = 1.1, Yn =?, Yn+1 = ?
n = 2, Xn = 1.2, Yn =?, Yn+1 = ?
