Core Numerical Methods: Algorithms for Computation
Implementing Euler’s Method
- Start
- Define function f(x,y)
- Read values of initial condition (x0 and y0), number of steps (n), and calculation point (xn)
- Calculate step size (h) = (xn – x0) / n
- Set i = 0
- Loop:
- yn = y0 + h * f(x0 + i*h, y0)
- y0 = yn
- i = i + 1
- Display yn as result
- Stop

- Read values of initial condition (x0 and y0), number of steps (n), and calculation point (xn)
- Calculate step size (h) = (xn – x0) / n
- Set i = 0
