We just started learning how to find diffrencial equations using the eulers method. I heard there is a programm in a calculator that lets you do that. I have a ti 84 I don't know the name of the program if you can be kind and give me the web site it would be appreciated. My calculus book had this question in which you have to find a point given the intial condition with dx like .05. Crazy! I was also wondering if you could use spreadsheet to plot and find the diffrencial equation easly. One more question :tongue: Can you find the exact solution if your dx approched 0 and is it possible to find an exact answer. Thanks for the help!
