Hello all, I have a very important test coming up in math soon and I would really appreciate if any of you can help me solve some problems in math, completing the square in trig. I am quite good in math otherwise but problems in function definition baffle me and I am at a loss. It would be extremely helpful if you can let me know of a reasonably priced software that I can use?

You can try out Algebrator. This software literally helps you solve questions in math very fast. You can plug in the questions and this product will go through it with you step by step so you can understand easily as you solve them. There are some demos available so you can also get to know how incredibly helpful the program is. I am sure your math, completing the square in trig can be solved faster here.
