What should I do to prepare for Precalculus?
Q. I have a decent background in algebra having taken Algebra I (beginning algebra) and Algebra II (intermediate algebra). My geometry background is sketchier. I have not taken a dedicated geometry class yet, although I am familiar with basic geometric concepts (but not all). I am going to take precalculus next semester. Does anyone have any pointers, advice, or preparation tips?

How many times did you take Precalculus and/or Calculus?
Q. How many times did you take Precalculus and/or Calculus in college? I mean, did you ever have to repeat any of them? Ifso, did you go on into a science or math discipline successfully even though you had to repeat?
Asked by Rock Paper Scissors - Sat Mar 7 02:57:42 2009 - - 2 Answers - 0 Comments

A. I precalculus once in high school and then again in college. College was much harder...proably the harder math I ever took ..unitl advanced linear algebra. I never failed a calculus course...much easier than precalc. Sure I think you can get into a science or math discipline. You wont be valadictorian but youlll make it. I took calc 2 over because that course is an important step in calculus and I felt that i should take it over...I didnt fail it though.

A. The TI-84 is a great calculator and will be just what you need. Here's a link to the least expensive one I found online ($99) from a reputable retailer that had it in stock: You can also search MySimon.com for this item to find other possible sources. Maybe also check Craigslist for a used one.

Is it true that you must take physics and precalculus in high school to major in pre med?
Q. My friend wants to major in pre med like myself but she isn't taking precalculus next year and she was thinking about not taking physics next year either. Doesn't she need precal and physics while in high school to major in pre med when she goes to college? My friend is a junior in college oops I meant she is a junior in high school not college
Asked by Misha J - Fri Apr 25 23:23:40 2008 - - 3 Answers - 1 Comments

A. There are not specific required classes you need to take in high school if you plan on being a premed in college. That said, if your friend wants to go into medicine she will need to be able to do both math (at least precalculus level) and physics in college, so taking those classes in high school isn't a bad idea. Also, it IS important to get into a good college, and many colleges do have math and other course requirements, so before your friend abandons math I would make sure that she's taken enough of it to apply to colleges with strong academic reputations. In college there is no such thing as a premed major--you major in whatever you like (biology, history, etc) and also take the series of "premedical prerequisite" courses--college… [cont.]

Precalculus At the End of This Semester?
Q. I am taking precalculus as an extra class to get myself ahead one year in math. I am taking it at a local community college, and getting credit for it at my school. My only concern is, since I am still taking Algebra II, will precalculus be any harder since I haven't completed Algebra II, and I am going to be taking the classes half way through the school year? I am an exceptional math student, and I love math and science. Do you think precalculus would be harder if you haven't completed the previous math course?

A. In my class, precalc and trig are combined into one class, but I'd have to say that if you're good at geometry, take trig since it's all about triangles and angles. However, if you're better at algebra, take pre-calc.

A. What, precalculus algebra? Pre-calculus is just precalculus. You learn equations, conic sections, trigonometry and other important functions and graphs you need to learn before calculus. Pre-calculus is super easy, you just need to stay awake during the course or if you decide to learn at home by yourself.

How do you set up these precalculus problems?
Q. I'm supposed to set up and solve these, though I'm not sure how. I know how to solve them using the column method, but I'm having trouble setting them up into a format I can recognize. X^4 < x^2 and x^3 < 3x^2 I am quite unclear on the steps. For the first one, I got x^4 - x^2 < 0, then x^2(x^2-1) < 0 I don't know if I'm doing it right. For the second one, I have x^3 - 3x^2 < 0, then x(x^2 - 3x) < 0 Still very unsure. Help is appreciated!
Asked by Jess - Sun Aug 16 17:23:57 2009 - - 1 Answers - 0 Comments

A. Hi Jess, you are totally on the right track, getting 0 on one side of the inequality, factoring and then doing a little sign analysis: In #1, keep it going to x (x-1)(x+1)<0. The factors provide zeros of 0, 1, -1, which would be the x-intercepts if you graphed the quartic y = x^4 - x . We are looking for the intervals created by -1, 0 and 1, in which the quartic expression is less than 0 (negative). That occurs (-1,0)U(0,1). In #2, factor out x : x (x-3) <0. The zeros are 0 and 3, We again are looking for the intervals created by 0 and 3 in which the cubic is less than 0 (negative). This occurs (- ,0)U(0,3). Neither of these change sign at the double root (at x=0), but they also don't include the double root because the… [cont.]
