With a bit more clear information about plotting 3d vector equations using maple, I will be able to help you if I knew particulars. If you don’t want to hire a algebra tutor, who is very pricey you can try this program Algebrator which I came across and guarantee to be the best available. This Algebrator is equipped to solve any math problem that you enter and it also clarifies every step of the solution. You only have to reprint as your homework. However, it is better to take the help of the Algebrator to learn algebra rather than use it to copy answers.
I remember having often faced problems with function domain, interval notation and slope. A really great piece of algebra program is Algebrator software. By simply typing in a problem from workbook a step by step solution would appear by a click on Solve. I have used it through many algebra classes – Remedial Algebra, College Algebra and Basic Math. I greatly recommend the program.
