... you are totally clueless ... you couldn't explain it if your life depended on it ... you are a poseur who hangs on Poppet's coattails and googles for stuff frantically to try to keep up.I understand algebra perfectly well, as well as geometry, trig, analytical geometry (calculus), and differential equations. I made straight As in Vanderbilt undergrad and Case Western Reserve MBA program. As a major land owner, I understand conversion from rectangular to polar coordinates. I understand the derivation of geometric properties (area, volume, etc.), velocity, distance, acceleration, etc. through the use of differentation and indefinite integrals.My brother is the mathemetician in the family, with a BS in Math from Yale and a PhD in Math and Physics from Stanford. I had no need to go beyond calculus and differential equations, as I rarely have occasion to use these disciplines in everyday life. My expertise is in business administration and computer science. I was CIO of a $15 bbn company for 13 years, and I persently own my own business with Fortune 500/1000 clients. Also, I was an Adjunct Professor of Computer Science at Vanderbilt for 13 years.Now crawl back in your vain shell and masturbate.
