Finding approximation using Euler's method

[asilvester635]

The answer for Question #1 is solved. I just need to know wether I did Question #2 right, specifically the "Compare y2 with the exact value of y you found in a". This is how I got the exact values. I plugged in dx=0.03 inside the solution that I found in Question #1. To find the second exact value, I doubled dx=0.03 to make it dx=0.06, I then plug that in the solution that I found in Question #1? Is that right?


UPDATE**** I FOUND THE ANSWER ALREADY. THANKS!
