What is the difference between pre-calc and algebra?
Q. I am halfway through my college level algebra course and i wanted to know what im getting into because i have pre-calc next semester. So, what is pre-calc generally about? How does is differ from algebra?

A. in precalc. you do lots of trigonometry, analytical geometry,matrices,probabi lity,vectors, Elementary functions( polynomial functions, rational functions,exponential and logarithmic functions) It is harder than algebra I and algebra II, but easier than linear algebra. Precalculus uses many techniques in algebra, so make sure you have a good foundation in algebra!

How familiar with Algebra should you be before taking Pre-Calc?
Q. I have a good understanding of algebra and should be able to pass college algebra without a problem, however because I don't have to take it, I am considering just jumping into survey of Calculus (pre-calc) but I have never taken calculus before and wasn't sure how much algebra is used, what should I do?

A. Algebra is utterly essential to an thorough understanding of both pre-calculus and calculus. If you're not absolutely confident in your ability to make at least a B (instead of "should be able to pass"), you will not perform well in calculus.

I failed my pre-calc course during my freshman year of college, can i still get into medical school?
Q. I go to one of the top 25 schools in the country & failed my pre-calc class my first quarter of freshman year. I did well on my other classes (B's & A's) . I am re-taking the class and it will still be seen on my transcript. Do you think this will hurt my chances of going to a good medical school or even getting in?

Could someone with little or no experience in Math go from Pre-Calc to a slew of upper level classes?
Q. What do you think? I'm in pre-calc now, I'm doing well, and I love it. I would want to pair the major in Mathematics with a Quantitative Economics major so I can more easily fit into graduate economics studies. Would it be likely that a person that hasn't had math in, say, 12 years could get through this with sheer hard work?
Asked by joshua_m_carpenter - Sat Feb 16 10:42:31 2008 - - 1 Answers - 0 Comments
A. No. If you have a sophisticated mathematical intuition, then not remembering all the details of calculus, etc. would not be a major problem. But if you don't have a good intuition about calculus, you can forget about doing well in economic theory. And if you don't have a solid grounding in linear algebra, you'll find quantitative economics very painful. There was also a time when you needed to understand differential equations to do well in advanced economic modeling. I don't know if that is still the case, but do you really want to take the chance? If you love math, take calculus and then go for the economics courses. It will make things much much easier.

How do you "find the greatest common factor and have the remaining ones integer coefficients" in pre-calc?
Q. My pre-calc packet asks me to "find the greatest common factor and have the remaining ones integer coefficients".. and I am a bit confused. Here are some of the questions that tell me to "find the greatest common factor and have the remaining ones integer coefficients": 1. 1/2x^3 + 2x^2 - 5x 2. 2/3x(x - 3) - 4(x - 3) If you could explain it to me it would really help, thanks

A. The idea is to take out the numerical factors so that what's left are just integer coefficients: 1. 1/2*(x)(x^2+4x-10) (factored out 1/2*x from each part) 2. factor out 2/3*(x-3): 2/3*(x-3)(x-6)

A. From my experience, students who are good at math continue to be good at math and meet the challenges of trigonometry, calculus, etc. So, if math has always come naturally to you, and you think you've got pre-cal down, I think it would be fine to go onto calculus. Now, the school may have a different perspective. Talk to your counselor and see what he/she says.

Should I Skip Pre Calc and go straight to Calculus?
Q. My math teacher says that because I'm doing so well, i can skip pre calc and go straight to calculus. My question is whether or not that would be a good idea. Take into consideration that I would be given a pre calc book to look over during the summer.
Asked by Gerald J - Tue Feb 3 22:32:19 2009 - - 10 Answers - 0 Comments
A. When I did pre-calculus a few years ago, I felt that it was mostly a rehashing of what we learned in Algebra II. If you feel up to it, you should probably just skip; however, I would recommend that you learn and fully master the trigonometry that is discussed in your teacher's pre-calculus book. Many of the trigonometric functions will appear frequently in your calculus class - you won't be able to do well if you don't understand them. Best of luck!

Can do well in AP calculus if I just take regular (not honors) pre calc: Should I review over the summer?
Q. I finished reg. Geom: A regular Algebra II: A and I am taking pre-calc next year and I am nervous if the transition from regular pre-calc to AP Pre-calc will be really hard. Should I review over the summer???

A. From my experience regular classes and honor classes are very different. Expect a lot more work in the form of reading, homework, critical thinking and working a lot on your own. I believe anyone can do it with some dedication. I do recommend you use your time now to get your feet wet with calculus. Get a book from the library and start working on at least the concepts. If you work on the problems that would be even better. Time you use now will benefit you when you are in class. P.S don't forget to review your algebra! a lot of students have difficulties with calculus not because the subject is hard but because they forget how to do the algebra. Good luck

Some descriptions: High school algebra focuses on setting up, solving, visualizing, and manipulating equations with unknown variables. Pre-calculus covers a range of topics, many of which are useful when you take calculus. The topics often include i. using identities to manipulate equations, ii. solving systems of linear equations, iii. complex numbers, iv. special, named functions, v. limits and sequences, vi. some geometry topics such as area.

A. let d = # of dimes let n = # of nickels let q = # of quarters 255 coins total: Equation (1): d + n + q = 255 Total $$ is $41.25: Equation (2): .1d + .05n + .25q = 41.25 Twice as many dimes as nickels: Equation (3): d = 2n Substitute d = 2n (Equation 3) into Equations 1 and 2: (1a) 3n + q = 255 (2a) .25n + .25q = 41.25 Multiply Equation (2a) by -4: (2b) -n - q = -165 Add Equation 1a and Equation 2b: (3n - n) + (q - q) = (255 - 165) 2n = 90 n = 45 Substitute n = 45 into Equation 3: d = 2 * 45 d = 90 Substitute n = 45 and d = 90 into Equation 1: 90 + 45 + q = 255 135 + q = 255 q = 120 45 nickels ($2.25) 90 dimes ($9.00) 120 quarters ($30.00)

How do I solve this Pre-Calc wind speed word problem?
Q. The average airspeed of a single engine aircraft is 150 miles per hour. If the aircraft flew the same distance in 2 hours with the wind at it flew in 3 hrs agaisnt the wind, what was the wind speed? I think you need to use more that one equation with more than one variable.

A. speed of engine with wind = x mi/hr speed of engine without wind = 150 mi/hr same distance = ( speed) (times) (x) (3) = (150) (2) 3x = 300 x = 100 mi/hr (It is slower speed, taking longer to travel)

My college gave me Calc and i never took pre-calc?
Q. Will i be able to survive? Is pre-calc needed for calc? What is pre-calc about?

A. i took precalc and it was basically just a review class. you review everything you learned from algebra 1 and 2 like graphing different functions (linear, exponential, logs) and a little bit of trig. it's not that big of a deal to skip precalc unless you forgot every single thing you learned in algebra.
