Question
Consider the ODE ƒ(x,y) = x – y. Take initial conditions xo = 0, Yo = y(0) = 11, x1
solve for y(30) with a step size of 0.2 using an adaptation of Euler's method, which uses two known y solutions to
approximate the next y solution. The general formula is:
= 0.2 and y, = y(0.2) = 22,
1
Yi+2 = Yi+1 +h
An example of the first few iterations is shown below.
Y2 = y1 + h
= 16.5600
Y3 = y2 + h
= 13.8920
Y4 = y3 +h
= 11.5204
What is the value of y(30) rounded to the nearest integer?
Note: Remember to round the final answer.
