I will do math problems up to calculus 3

I am getting a Computer Science and Applied Mathematics degree from a very respected institution. I am currently taking calculus 4 and will do math problems up to calculus 3. Please note that I won't do ALL calculus 3 problems as some get too long and complex to be worth $5. However, some are simple and straight forward. Please CONTACT ME WITH THE PROBLEM before purchasing this so I can verify that I can do it for $5. Thank you!
