Math 150A Project Spring 2013

Part 1: Writing Assignment.
(20pts) On Titanium you will find two options for your writing assignment. Choose and do only one.

Specifics:
Writing in a math class can sometimes be difficult. Here is a site that you might find
helpful: https://edisk.fandm.edu/annalisa.crannell/writing_in_math/guide.html

Your writing assignment must be typed or written in ink. If you decide to type it, your
assignment should have 1-inch margins and you should type in Times New Roman or
Arial font size 12. Feel free to write in diagrams or notations.

Part 2: Calculations

You must show all your work. No work or lack of work means no credit. This second part must be
written using pencil only. Failure to follow directions will result in loss of points. Work that is too
hard to follow or lack of organization will result in loss of points.
