Chemical Engineering 132A Analytical Methods of Chemical Engineering Professor Mike Gordon, Fall 2011 Mathematica Assignment #1 If you do not finish during recitation, turn in your completed assignment by Monday, 3 October 2011 . 1) Define the following functions: ( x e x f x 2 cos ) ( 2 - = ) sin( ) ( 3 x x x g - = ( 29 + + = 1 2 3 4 log 2 4 x x x h 2) Evaluate each of these functions at x=2. Give both symbolic and numerical answers. 3) Plot each function on the domain [0,3]. 4) Define 3 new functions which are the derivatives of f, g, and h.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
