Need math wizard to help with statistical type problem for study

Must be proficient in math especially calculus. Must be able to properly show steps taken to solve equations so I can document the results for later use. By accepting this project you agree not to disclose the information involved in the project. Also, I will take sole ownership of the results you provide. I would like you to bid on the completion of 50 such equations. If you would like, you could offer a cost "per question" amount and we can negotiate a set number of problems for you to complete. There will be more work in the future if we find you do the perfect job. I am looking for speed and accuracy. Someone with access to collaboration package Teambuilder (see [login to view URL]) is a plus. An example problem is the following: * @f=@x and @f=@y for the function f*(*x; y; t*) = 5*t*4 *?* 4*t*5 cos(*t* sin *t*) or Use the Law of Sines to model and solve real-world problems.
