## Homework Statement

dy/dt = y^2-4t - y(0) = 0.5 - 0 <_ t <_ 3.0 - Change in t = 0.5

I have to use Euler's method to make a table, but I'm not sure how to handle the t. I have only done it with y's and no other variables.

[tex]

y_{i+1}=y_{i}+hy'(t_{i},y_{i})

[/tex]

So in your case the equation would be:

[tex]

y_{i+1}=y_{i}+h(y_{i}^{2}-4t_{i})

[/tex]

Understand now?

K: 0

t:0

y:0.5

dy/dt(t,y) = .25

Change in t*dy/dt(t,y) = .125
