Use Euler's method with the given step size to estimate y(1.4) where y(x) is the solution of the initial-value problem

y'=x-xy, y(1)=1.

1. Estimate y(1.4) with a step size h=0.2.
y(1.4)?

2. Estimate y(1.4) with a step size h=0.1.
y(1.4)

Use Euler's method with step size 0.25 to compute the approximate y -values y1,y2, y3, and y4 of the solution of the initial-value problem

y'=1+2x-4y, y(1)=-4.

y1= ,
y2= ,
y3= ,
y4=
