Use the Improved Euler’s Method with h = 0.2 to approximate (to 4 decimal places)

the solution of y' = −2xy , y(0) = 3 on 0=<x <=1 . Compare your approximations with

the true values by calculating the errors.

Am not sure how to start everytime am doing this my values are just gettin bigger and bigger wen thier supposed to go smaller???

isnt the true solution e^-x^2

my y1=2.88 y2=2.93? what am i doing wrong!
