What Math Skills Are Needed for General Physics?

[nomilkforsant]

This is my first post, so I hope am writing it in the correct sub-forum.


Hello guys,

I am a post-bachelor, pre-med student that will be starting the general physics requirements in the fall (2011). Medical schools only require algebra based physics, and the vast majority have dropped the calculus requirements. The highest math class I completed was College Algebra and Trig, which is all that is needed in general physics, however, that was over 3 years ago.

My girlfriend has convinced me that I need a strong algebra background with a general understanding of the trig functions to do well in general physics. Can anybody recommend a good workbook or college textbook that will allow to drill problems? Also, what specific types of problems should i be focusing on?

Thank you,

Nathan.

Focus on the Pythagorean theorem, the definitions of sin, cos, and tan, and rational functions. The math in intro physics is technically very simple (most of the math in my calc-based course was arithmetic only). The difficulties lie in setting up the problems themselves. Be comfortable with your algebra and trig, but the math in physics is really something you learn only in physics.

She's right. You need at least basic Trigonometry and strong Algebra skills. Give yourself about 4 to 6 months and review College Algebra and Trigonometry what good reliable textbooks. I suggest College Algebra just to help your analytical thinking, but you can still review Algebra well enough at Intermediate instead.

If you decide to go into the Calculus based courses and need two semesters of Calculus, and if you have credit for College Algebra And Trigonometry, you might be permitted to just enroll in Calculus 1. You could then enroll into the Physics 1 (whichever is the first fundamental course) when you are ready.
