Next we fill in y on the next row. We know that we should have y(2) is approximately y(1) + h y'(1). We will fill this in to row two column two using a formula based on row one, which contains values for y(1)_and y'(1). We use the formula =B2+1*C2 in cell B3. For the y' entry, we can copy the entry from row two, since we used a formula. This gives us the following in our table:
A 
B 
C 

1 
t values 
y values  y' values 
2

5 
3

Finally, since everything in the y and y' entries of row two is a formula, we can fill down (or drag down) the two entries in row two to the rest of our table. When Excel finishes calculating, we get the following:
A 
B 
C 

1 
t values 
y values  y' values
