I messed around too much in high school so I never got into any advanced math. Are there any good books(maybe like the for dummies series or something)? I know these classes will kick my ass so I want to get as much of an understanding as I can before heading into the classes.
 12/10/07 7:17 AM Ignore | Quote | Edit | Voolf Edited: 10-Dec-07 Member Since: 10/04/2005 Posts: 125 I was a TA for a trig class this semester, so I have some tips! First and foremost, you need to do a lot of problems. Do every homework problem that is assigned, even if it's not graded homework, and as many other similar problems as you can. A book with extra problems would be great, too. Schaum's Outlines are usually pretty good, and they usually have explanations and solved problems too, which can help supplement your textbook. I checked Amazon and the "Trig for Dummies" book gets good reviews, so it might be good to have as well. Second, make use of the resources you'll have available. Go to your professor's/TA's office hours and clear up anything you don't understand in the homework. If your school has a math tutoring center, go to it and ask questions. These classes can move pretty fast, so you really need to stay on top of things to keep your head above water, especially if you aren't already familiar with the concepts from high school. Of course, you should go to class! Get a good professor, if you can. It really can make a difference. One professor in my school has averages on exams in the 80%'s, another has them in the 50%-60%'s. I know which professor I'd rather have! Good luck!! You have ignored this user.

I'm sure I'll end up in the tutor center a few times. I'll be making a trip to pick up some books in the next week or so to get a head start. It'll be a good time going from 6 classes and "semester break" that ends up being more studying. You have ignored this user.

That's pretty strange; in that case, you probably should seek out as many different study materials as possible, just to get as many explanations of the topics as you can get. Hopefully at least one of them will make sense to you! Definitely don't be shy about going to the tutor center; you might struggle with a problem for an hour on your own, while it might take 5 minutes to get it cleared up with a tutor. You don't have to pay to use this place, do you? I hope not! The easiest thing to do would be to do the problems for a section, not spending too much time on any problem, and then go get help on any problems you weren't able to do quickly on your own. That gives the tutors something concrete to focus on and makes it easier on them. Work through the problems on your own again afterwards, just to make sure you really understand the material, too.

I never did homework and alwasy tried to study the day before. Therefore I never passed it. Trig I passed the first time with a B+. I would suggest doing your homework and studying in the math lab if you have one. I think the key to passing a class like this is having a math center and having a tutor explain the stuff to you. Most the concept in Trig are easy to understand after they're explained to you. Sometimes it can be impossible if you're trying to figure it out on your own. You have ignored this user.

The site we're using is really cool as it has a step by step break down of a similar problem if you need help on it. I'm spending quite a bit of time on the homework and haven't missed even a partial point in 90 problems for the last 2 weeks. Actually seems like it'll be one of my easier classes at this point. The 2 books that I picked up helped wiht some basic concepts. You have ignored this user.

 10/23/08 12:53 AM Ignore | Quote | Edit | sepe Member Since: 1/1/01 Posts: 25294 lol man...calculus is fucking confusing. doing the problems isn't helping a whole lot either. the prof(had him for another class and I know many others that have had him) but it is like he is speaking japanese. Continuity, limits, and asymptotes are the things that are confusing the hell out of me. Graphing or approximating limits/functions from a graph make no sense. I had picked up some books on trig last spring semester and ended up getting a high C out of the class. Felt pretty good about it because I failed geometry in high school once I stopped playing football. I'm heading to Barnes & Noble in the morning to look for a book or 2. Doing over 100 problems a chapter hasn't really helped that much. Need ot find something that will help with the limits, derivatives(not too confused there), and multivariable calculus. I checked with the tutor lab for the math tutors...none for calculus. Books that break it down into words will help a bunch though. _____________________________________________________________________________ Just seeing an example of say f(x) = x^2+20/5(x-2)^2  n(x) = x^2+20 and d(x) = 5(x-2)^2. since d = 0 only at x = 2, f is discontinuous only at 2. since n(2) = 24 ≠ 0, f has a vertical asymptote at x = 2. tables 5 and 6 show that f(x) ---> infinity as x ---> 2 from either side and we have, lim x--> 2+     x^2+20/5(x-2)^2 = $\infty$ lim x--> 2-      x^2+20/5(x-2)^2 =  $\infty$  table 5 x         | f(x) x^2+20/5(x-2)^2 2.1       488.2 2.01     48,080.02 2.001   4,800,800.2 table 6 x         | f(x) x^2+20/5(x-2)^2 1.9        472.2 1.99      47,920.02 1.999    4,799,200.2 denominator d has no other zeros, so f does not have any other vertical asymptotes. with the left and right hand limits both infinite, we have lim x--> 2     x^2+20/5(x-2)^2 = $\infty$ does all of that actually mean anything to anyone? it sure as fuck doesn't to me. I don't understand when I'll use it but the frustration is making me want to learn it enough to be able to do more than just a passable job(even if I have to learn it more on my own after barely passing the class).

 10/28/08 4:14 PM Ignore | Quote | Edit | Respect Member Since: 9/21/05 Posts: 3074 I know fuck all about math. I can figure out x can't be two, because if it was, then you would have x^2+20/0. So, using common sense, there would be an impenetrable line running on two. That stuff doesn't look hard at all. You should try harder and quit crying. You have ignored this user.

I don't understand when I'll use it but the frustration is making me want to learn it enough to be able to do more than just a passable job(even if I have to learn it more on my own after barely passing the class).OK what is the problem here? Continuity: Just look at the function as a graph. If there are jumps at certain points, it is discontinuous. Just about every function you will see will be continuous, unless it's defined piecewise.Limits: Just means that the function approaches some value. E.G. 1/x approaches 0 as x gets larger and larger. Look at a graph of it. You will see what I mean. All a limit is is what a function behaves like 'near' a certain value.Asymptotes: Related to limits. 1/x is asymptotic at f(x)=0. Again look at the graph.lim x--> 2 x^2+20/5(x-2)^2Easy. This function is not definef At x=2 you are dividing by zero so the function approaches infinity. Think of it this way. When you divide, you will get a bigger number when dividing by a smaller number, so in the limit as you divide by 0, your result keeps getting bigger and bigger (approaches infinity) Man I wish I could explain this better but i'm too drunk.

 12/8/08 1:18 PM Ignore | Quote | Edit | big fatso 8 Member Since: 12/19/07 Posts: 3217 I used to tutor calculus to a wide variety of people privately and at a local community college (from AP Calculus students all the way to middle aged soccer moms). Based on the information I gathered, I am of the opinion that most people fail first semester Calculus not because of any conceptual difficulties within the course (though they are certainly compounded), but they do so because of rotten foundations in Elementary Algebra and Trigonometry. Without knowing any Calculus at all, you should've been exposed to both continuity (though at an extremely rudimentary level, e.g., "when you can draw the graph without lifting your pencil from the paper") and asymptotic functions (f(x) = 1/x) in an Algebra II course. It will only get worse once you get into finding the derivatives of trigonometric functions. My advice: Brush up on Algebra and Trig, and do so seriously. After that, get a textbook and "How to Ace Calculus," and you should be golden. You have ignored this user.
