"Advanced" PreCalculus? That's Calculus, isn't it?
Hello. I'm studying for a college entry exam, and the subjects covered are roughly equivalent to precalculus in the American education system. But the problems are more advanced than that.
I have a few books that have similar problems, but they don't have any tips how to solve them, and the books that give tips for solving are on a very, very basic level and don't help at all. The result is that I have to figure out everything by myself and it's going pretty slow.
I've attached two types of example problems, and these are one of the easy ones: and
Another type of problems include all kinds of functions, geometric problems, combined geometric problems and functions, trigonometric equations, arithmetic/geometric series word problems or all of these combined.
I'm looking for books that cover this kind of problems, preferably the ones that can be bought via Amazon.
Thanks.
