Slide rules used two rods on which units are measured

This preview shows page 11 - 12 out of 12 pages.

, slide rules used two rods on which units are measured and marked in logarithms ( i.e. 10 log x ), but with corresponding labels marked with the underlying number itself ( i.e. x ). Thus, while you use the rods to add 10 log 2 to 10 log 3 , to obtain 10 log 6 , the labels on the rods show the multiplication 2 3 to obtain 6. The drawing at the top of this section illustrates this idea. The corresponding interactive Excel model appears in the Spreadsheet Models section of the Web site. Incidentally, since we are operating in base 10, the same mechanical computation also provides us with the answer for the products 200 0.0003 or 12 5 (2 10 ) (3 10 ) , except that you must keep track of the decimal point manually. 5. Another field that provides mathematical examples accessible to all university mathematics students is operations research (OR). Illustrate ideas found in related OR texts for one or more of the following topics: linear programming; game theory; inventory control; queuing theory; hill-climbing algorithms; and 11

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
