Think about it...why would you want to come ask a question, wait 5-10 minutes, then get an answer, when you can just go through the section in your textbook and find your answer there in half the time or less? By logic, it would make more sense to check your book first. I know that the constant rule for limits is in there somewhere. I own six different calculus books, and I can find that rule sticking its nose out in the open in every, single one of them.
It's an important life skill. Sometimes you won't have us to help you: it may be just you, your lecture notes, and your textbook(s). Get comfortable with your textbook. A LOT of high schoolers (including me at one point) saw math textbooks as just books full of exercises, and we highly underestimate its capabilities in assisting us. It wasn't until I started college two weeks ago that I began to recognize math textbooks as the true treasure chests they are. It has provided invaluable assistance in many things that I have had questions about, and has saved me countless hours of constant Q & A sessions with people on here, my classmates, as well as my professor. I've actually been able to tutor some of my classmates on concepts from the book that they didn't quite get.
I'm a math major as well as the biggest math nerd you have ever met in your life. Maybe these things I'm saying to you comes naturally to me, and not to other people. That's fine. I've come to accept that not everybody loves math like I do, nor do they have that gift for it. But what I have said to you this evening can not only help you in math, it can help you out in your other courses, in college, graduate school, your job, wherever you could possibly go.
Hopefully you'll get something out of my little rant for this evening. I wish you the best on your future endeavors, and we'll always be happy to assist you should the need arise.
I have to agree with the above post. Throughout my schooling, I noticed that so many students didn't even bother to glance at the lesson sections within math books. If a problem stumped them, they would either immediately run to somebody else for help, or just give up. I learned early on in my studies of math that sometimes you just have to try and teach yourself a little. Many of my teachers were very surprised when I mentioned that I actually read the book.
