None of these questions are homework problems, they're just confusing things that homework has caused
1. In math, what is the difference between a bracket and a parenthesis? Also what about the right symbols for ordered pairs , is that strictly these [ ] or these { }
2. If you have lots of brackets (just to be clear, I mean these ( ) )... does the number of left hand brackets always equal the right hand brackets? For example,
## f(x) = (3(x^2 - 3) / x(x^3+6)) ## I realize it could be written a lot different, but I am just focused on the brackets.
..so when you are checking over a long problem, you can count the left brackets and make sure they = right brackets. Is that valid? (in English one right bracket can close multiple left brackets, which has never made sense to me. So math is different?)
3. What is he difference between "broadened" and "steepened" wrt graphs?
4. Are corners of a function defined and how do I know they are defined? (or does it all depend on the function?
5. What does the textbook mean when he says "use analytical method to determine..." Is he just saying make a graph and look at it?
6. Conic sections: Why are hyperbolas represented with two lines , taken from two cones, when circles and ellipses are represented using just one cone?
thank you for any answers
