Let y(t) be the solution to y=7tey satisfying y(0)=2.
(a) Use Euler's Method with time step h=0.2 to approximate y(0.2),y(0.4),,y(1.0).
(b) Use separation of variables to find y(t) exactly.
(c) Compute the error in the approximations to y(0.2),y(0.6), and y(1).

Step 3
y=dydt7tey - (1) y(0)=2 -(2)
dyey=7tdt
eydy=7tdt+c
ey=7t22+c
Using (2) we get,
e2=c
ey=7t22+e2
y(t)=loge[7t22+e2]

Step 4
y(0.2)=2.0188|(y(0.7)y1)=|(2.01882)=0.0188now y(0.6)=2.1574|(y(0.6)y3)=|(2.15742.11078)=0.04662y(1)=2.3878|(y(1)y5)=|(2.38782.3351)=0.0527
