Mathochism: Brain nudge
One woman’s attempt to revisit the math that plagued her in school. But can determination make up for 25 years of math neglect?
When taking pre-calculus, we were told that that would be the last course that reviewed any of the old material. In other words, if we hadn’t learned WTF absolute value was, we were absolutely effed.
This appears to have been a lie. My first week in calculus (I’ve been a calculus student for a week now. Yay!) was all about intermediate algebra and trigonometry. The actual calculus begins next week (Eek?).
I’m not complaining, mind you. It’s barely been two months, but my brain needed a nudge on things like identifying zeroes in a root function and trig identities such as 1 + tan^2x = sec^2x. I hadn’t forgotten, exactly, but these concepts were likely obscured by holiday food and “Ghost Hunters” marathons.
The Calc Professor (nope, no clever moniker yet) has been rather heavy-handed in pointing out that fresh pre-calc skills are required to do well in his class. Anything over a semester away from sines, in his opinion, just won’t do. (He even put this in two different places on the syllabus.)
I can see his point, though, because I think one reason I failed my first pre-calc test in the dropped summer class was that it had been more than a year since intermediate algebra. I was rusty! And tired, since the class started before 8 a.m. And let’s not even mention the Brofessor… Oops, I guess I just did.
But back to calculus. I wound up buying a book at the illicit store across the street from the college and canceling on Amazon. It only cost me a bit more for this book, and the price I paid is 60 percent less than for a new copy. My used copy has all its pages, has not been scribbled on, and doesn’t smell like vomit. It does, however, look like it’s been run over a couple of times and then left out in the rain.
It still cost almost $100! As blog is my witness, I plan to find out why in hell math books are so expensive. And will we ever see them on an e-reader?
All right, time to tweak my grey matter with a few trig equations. It might help to have “Ghost Hunters” on in the background.
