So, somehow, I’ve made it through two tests in pre-calculus. Let’s just say that it is unlikely that I will get an “A” in this class, but a “B” is still in the cards. Failing is looking somewhat more remote, but remains a possibility. A review of our test this morning reveals that I have the basic concepts firmly under control, but the details are bedeviling. For example, asked to find “all exact zeros” in a polynomial, I perfectly executed the determination of possible rational zeros, using my new best friend, the TI-86 calculator, selected my zero, and divided the factor into the polynomial. That yielded another polynomial, which I used to solve for “x” by plugging values into the quadratic equation. I got an answer that included a rational and two irrational numbers. Looked good, so I moved on. Only thing is that I reversed the sign of the constant in the second polynomial. You college grads will know what that means. The professor grudgingly gave me one point out of six for the process. Disaster jerked from the jaws of success.
But all that is, as they say, but a distant memory. I will revisit my old friends next week for the Final, but for now, it is on to trigonometric functions, a subject that I have never seen, never been taught, don’t understand the concept of, and, which,according to my professor, will be the most difficult part of the course.
Does anybody have a gun?
