Recall that Euler's Method for solving a first order initial value problem is given by

y(0) = yO y(i+1) = y(i) + h*f(t(i),y(i)), i = 0,1,.....

Write a main program and accompanying subroutines/functions
that will implement Euler's Method for solving the first order initial
value problem

- a)
- At a minimum, you will need a subroutine for implementing the
main Euler's Method loop and a function to evaluate
*f*(*t*,*y*(*t*)). - b)
- You will need to input a value of
*n*and define

as we have been doing. - c)
- Your main program should compute the exact solution, the error vector and the 2-norm of this error vector (the subroutine you wrote in HW 24 will be useful here).
- d)
- One tricky aspect of the problem is that in the Euler's Method pseudocode above, the subscripts on the variables start with index 0. Fortran subscripts start with index 1, so you will need to account for this.

Use your program to compute an approximate solution to
the problem

Use separation of variables to compute the exact solution. How large must

NOTE: This is an evaluation assignment. It is essentially an
informal take-home test where you can ask questions. However, you are limited
to a maximum of 5 emails per day (5 today and 5 on Thursday). I will be
in the office on Thursday from 11:45 - 12:45 and 3:15 to 5:30. I will not be
in my office on Friday morning.
