For the Euler polynomials, use euler with two input arguments. Compute the first, second, and third Euler polynomials in variables x, y, and z , respectively: syms x y z euler (1, x) euler (2, y) euler (3, z) ans = x - 1/2 ans = y^2 - y ans = z^3 - (3*z^2)/2 + 1/4. If the second argument is a number, euler evaluates the polynomial at that number.One step of Euler's Method is simply this: (value at new time) = (value at old time) + (derivative at old time) * time_step.
