I have a ti-89 so it can do both limits and derivatives and I use it mostly just to check my homework. I also have a ti-83plus because 89's arent allowed to be used on the exams. My problem is sometimes I cant figure out how the 89 is giving me a certain answer. so even though its right I'm not really learning anything because it doesnt show how it got there.
I was wondering if anyone knows of a program or some way to on either an 83plus or a ti-89 the do limits and/or derivatives but have it actually show the work of what its doing.
I did a search but wasnt able to find anything very helpful but I apologise if this has been covered.
