Query: I wouldn't recommend it

I had a difficult time understanding pre-calc, so when I went on to Calculus, I thought I could use some extra help. But honestly, this program is not worth the money.Mainly, there is a lot this program cannot do. For example, there are several symbols used in calculus that are not available on this program, including delta, which gets used often in calculus. So if Delta, or any of the others, appear in one of your complex functions, you are SOL.You are also limited on your answering options. For example, if you need to "evaluate the difference quotient", too bad. You can solve for Y, you can solve for X, and you can graph it (provided you could enter in the problem in the first place), but that is about it.I had high hopes that this program would help me learn Calculus, but because it is so limited, it can't even handle Chapter 1 of my book. I would not recommend spending the money for this program.
