Ordinary Differential Equations Question!!!

Find the local truncation error (LTE) for the following numerical method of solving the IVP y' = f(x, y) , using uniform step size h. y(x0) = yo h2 yit1 = yi + hf(xi, yi) + 2 [fa(xi, Vi) + f(xi, yi) fy(Zi, yi)] Hint: dy = f(x, y) =f = d'y = fat fuzy= dy dx = fr+ fyf, by using total derivatives and chain rule
