2. Optional math review question not for credit, but. this might be good to refamiliarize yourself with how to take complicated derivatives: (a) W' hat is an ant iderivative of a function? (b) Show that. 1' y2 $2 + {92 3 is indeed an antiderivative of 1/ 1/13 + 342 with respect to a: (as I claimed in class when I derived the electric eld around an innitely long string). (c) Are there other anti-derivative of 1/ \\ Mfg + 3/2 w1th respect to :13? If so, do we need to correct. the result for the electric eld derived in class
