Using a step size h=0.05 and the Euler method, butretaining only three digits throughout the computations, determine approximate values of the solution at t=0.1,0.2,0.3, and 0.4 for each of the following initial value problems
a) y'=1−t+4y,y(0)=1
b) y'=3+t−y,y(0)=1
c) y'=2y−3t,y(0)=1
Compare the results with those obtained in Example 1 andin Problems 1 and 3. The small differences between some ofthose results rounded to three digits and the present results are due to round-off error. The round-off error would becomeimportant if the computation required many steps.

Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.arrow_forward
