Depends on what you're after. I'm studying Biotech, and I enjoyed his book "Biocalculus" because it teaches how to apply mathematical & statistical models directly to biology. However, I've heard Stewart lacks mathematical rigor, and people who are studying pure mathematics sometimes prefer authors like Spivak and Apostol. Those are more difficult, but will teach you how to think mathematically.

So, the main question to ask yourself is this: Why am I studying mathematics? How does this book further my long-term goals?

In order to have a strong intuitive understanding of trig, you need to be comfortable with the unit circle definition of trig functions, and thinking about problems in those sorts of terms. Pic related.

In math in general, it's very easy to fall into the trap of trying to memorize what symbolic manipulations are valid to solve the sort of problem you might be given. Don't do this. If it hasn't started to fall apart yet, it will eventually as the material gets harder. Everything technique you use to solve a problem is grounded in something which should make sense. You should understand why you're allowed to do things, why the formulas you use work. You should be striving to understand why what you're doing is valid, not memorizing the things which are valid.

Can we get a homework general started? I know that homework threads are against the rules, but people are going to keep breaking the rules anyways. Let's contain all of the homework in this thread, so please post your question here rather than making a new thread.

I don't see why there should be any problem with this, if anything it's helping clean up this board.

Oh and please keep it math and/or science related.

Yes, it's ridiculous. When I finally found out that sin e and cosine and tangent really came from the unit circle I felt like I'd been cheated.
