Would it be possible to buy a trig text book and read it straight through and teach myself? Do people do this? I know that it is very hard to teach yourself calculus, but isn't trig much easier to teach yourself?
I taught myself computer programming (go QBasic help! ) and was actually surprised how SIMPLE math functions were. I was used to having a function... DO stuff... and not just return a value. So it was really like a step down.mathwonk said:one other thing that also holds many people back is not knowing what a function is. i.e. most people think a function is a formula, rather than a pair, namely a domain, plus a rule for assigning values to each element of the domain.
I disagree. I'm quite young, and haven't had loads of maths experience.programming will teach you bad habits, and even then it isn't a good idea.
That strikes me as a peculiar thing to say. It is not unusual for secondary schools or even colleges to have courses name "trigonometry" and certainly there are many textbooks on "trigonometry". Perhaps you are using the word "subject" in a very precise sense?mathwonk said:the point is there is no such subject as trigonometry. there are basically two trig functions, sin and cos, and you should know something about these two functions.
Saying trigonometry is a subject is like saying x^2 is a subject, or maybe that quadratic functions are a subject.
Isn't about half of pre-calculus trig anyway? I'm not saying not to go through it all, but it's good to have a solid background in trig. Especially when you get into Caculus III and deal with vectors. I've had to do some review on trig when I did that.Tom McCurdy said:because if you are worried about being prepared for calc
skim through a precalc book and see if you understand the material after you study some trig
