Question:When taking the Ged are you given a formula chart for the math and science sections? Do I need to memorize the formula's or will they give me a chart with the formula's on it?
Answers:Yes, the math section comes with a list of formulas such as the area of a square, circle, etc. But you should try to have them memorized anyway. Although I was surprised when I took the test that most of the formulas you don't use at all.
I don't think the science section had a formula chart. I can't think of what formulas science would have.
Question:Im wondering if any of you guys can give me advice about a current issue i'm having.
I'm placed in a low remedial math class, its basically pre-algebra.
I took a accuplacer test and did not score well.
so now im a math class that reviews long division, multplying and fractions and such and basic algebra questions
I feel like i got completely fucked on though, the accuplacer test i took was testing me on things like polynominals, functions and some stuff i had no clue how to do, i was able to do the functions/polynominals.
I've never been great in math but in high school i took pre algebra, geometry and algebra 2 with a intro to pre calc class that was just more advanced algebra class.
if i was able to use my TI calculator on the accuplacer test or if it actually tested me on things I learned in the past two years i would of been fine, but it was asking me problems i had zero idea how to do.
im just really angry because i now have to pay money for someone to teach me how to do long division and basic algebra equations and then after this i will have to take a intermediate algebra class.
is there anything i can do besides stick it out?
Answers:Go online and check for "free math questions" find a good site and practice
Answers:No formula sheet, though more than likely, you won't have to calculate anything that requires some obscure, rarely used formula unless they give it to you in the problem.
Question:I have been out of college for 6 years and am just now going back to school. I had to take a college level math placement test and didn't do so well. One of the questions was something like "how many radians are in an angle of 18 degrees?" I was just on wikipedia looking at equivalents and it says that 180 degrees = pi. So is 18 degrees pi/10? Is this all a matter of memorization? Or is there an easy way to calculate these things? These placement tests are no calculators.
Answers:Math is mostly considered by how good you are at logic, but you must also be good as memorizing formulas.
To get Radians from degrees you will use this formula:
So if you put 18 in for the angle you will end up with (18*Pi)/180 Simplify that and you can get 18 to equal 1 and 180 to equal 10. So it is (1*Pi)/10. Which the 1 is understood so it would be Pi/10.
To get degrees from radians you use this formula:
So if you put Pi/18 in there you will get (Pi/10)*(180/Pi) You can then cross out the Pi's and you will be left with (1/10)*(180/1) which is (180/10) which is 18.
College Algebra: Decoding the Circle Formula :watch full lesson here: www.mindbites.com This lesson is part of a series: College Algebra In this lesson, you will learn how to find the (x, y) coordinates for the center of a circle graphed on the Cartesian coordinate system as well as the the radius of the circle from a formula or expression that doesnt easily lend itself to the standard circle formula (eg r^2 = (xh)^2+(yk)^2)). To do this, you'll generally use a math technique called, Completing the Square. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, College Algebra.
