No don't worry --
My teacher didn't assign us this problem... he asked us to "find a calculus student and have them find the derivative of this function". He wasn't asking us to do something we didn't know how to do; more likely he was trying to bug some of his calc students by having us follow them around asking for derivatives.

Thank you both soo much though!
