man, you must really like numbers if you\u2019re thinking about taking the math 2 sat subject test. it\u2019s all cool, though, since i really like numbers too! here\u2019s a couple of pointers to help you study for the test. i\u2019ll be referring to practice questions from the college board\u2019s website<\/a>, so take a look at them as you read along.
\n <\/p>\n

tip 0: read this post<\/a> on how to take the math 1 test.<\/h3>\n

there are differences between the math 1 and math 2 subject tests. however, a lot of the strategies i wrote about studying for the math 1 test will carry over to the math 2 test. look over those tips and try out some of the practice problems to get a head start on prepping for the math 2 exam.
\n <\/p>\n

tip 1: get friendly and freaky with functions.<\/h3>\n

there are a lot of questions about functions on the test. of the 28 questions that the college board provides, 11 of them are related to functions. and those questions usually go far beyond the usual “if f(x) = 2x + 1, what is f(3)?”<\/em>\u00a0variety. you should know the definitions of domain and range and understand how to apply them to any particular function the test throws at you (see question 15). you should know how to graph functions and find their maximum and minimum values (see question 9). and, you should know how to find a function\u2019s inverse, or how to define a function given its inverse (see question 25).<\/p>\n

in addition, there are also function word problems that you need to understand how to solve for as well. take question 21:<\/p>\n

in january 1990 the world\u2019s population was 5.3 billion. assuming a growth rate of 2 percent per year, the world\u2019s population, in billions, for t years after 1990 can be modeled by the equation p=5.3(1.02)^t. according to the model, the population growth from january 1995 to january 1996 was:<\/em><\/strong><\/p>\n

(a) 106,000,000<\/p>\n

(b) 114,700,000<\/p>\n

(c) 117,000,000<\/p>\n

(d) 445,600,000<\/p>\n

(e) 562,700,000<\/p><\/blockquote>\n

hey! this looks a lot like one of those \u201creal-life application\u201d questions at the end of the textbook chapter that you skip over because ain\u2019t nobody got time for that<\/em>. make time for them now, since these type of questions will pop up in the math 2 test. luckily, this question gave you the function, so it\u2019s up to you to figure out for what values of t you want to evaluate. once you have that, you\u2019re pretty much good to go.<\/p>\n

tip 2: seek out the right triangle.<\/h3>\n

in addition to there being a lot of function questions, there are also going to be a lot of geometry questions. taken together, functions and geometry will be about \u2154 of your test, maybe even more. they will link together different aspects of basic geometry, like finding the volume of a 3d solid, and coordinate geometry, like finding the area of a shape with vertices at (x1, y1) (x2, y2) etc. that\u2019s\u00a0square one.<\/p>\n

#geometryjokes #sorrynotsorry<\/em><\/p>\n

then, they will throw things like question 7 at you:<\/p>\n

a right circular cylinder has radius 3 and height 3. if a and b are two points on its surface, what is the maximum possible straight-line distance between a and b?<\/em><\/strong><\/p>\n

(a) 3\u221a6<\/p>\n

(b) 3\u221a5<\/p>\n

(c) 6<\/p>\n

(d) 3\u221a3<\/p>\n

(e) 3\u221a2<\/p><\/blockquote>\n

chances are pretty good that if you\u2019re given a geometry question without an obvious pathway or formula for solving it, you\u2019re going to want to find a right triangle somewhere. you\u2019ll have to visualize 3d shapes in a slightly different way. you may even have to rotate them around in your mind to spot the right triangle. but rest assured it\u2019s there. if you\u2019re stuck, here\u2019s a little hint<\/a> that might help you out.<\/p>\n

as a side note, sohcahtoa will be one of your best friends for coordinate geometry problems. check out questions 18 and 22 and you\u2019ll see why.
\n <\/p>\n

tip 3: don\u2019t forget about the small things.<\/h3>\n

while studying functions and practicing geometry will get you pretty far in the math 2 test, there are still a good chunk of questions left over. unfortunately, pretty much anything you learned in algebra, geometry, trig, and even pre-calc and statistics are fair game. fortunately though, the questions that they will ask are relatively straight forward and basic, like question 19.<\/p>\n

for a class test, the mean score was 65, the median score was 71, and the standard deviation of the scores was 7. the teacher decided to add 5 points to each score due to a grading error. which of the following statements must be true for the new scores?
\n<\/em><\/strong><\/p>\n

i. the new mean score is 70.
\nii. the new median score is 76.
\n<\/em> iii. the new standard deviation of the scores is 12.<\/em> <\/strong><\/p>\n

(a) none<\/p>\n

(b) i only<\/p>\n

(c) ii only<\/p>\n

(d) i and ii only<\/p>\n

(e) i, ii, and iii<\/p><\/blockquote>\n

you don\u2019t need to bust out any weird regression formulas, or even know the exact formula for calculating standard deviation. however, you do need to understand what happens when you change your data set. with this question, what actually happens to your stats when you add 5 points to everything?<\/p>\n

a lot of these questions test you more on mathematical concepts than on actual calculations. don\u2019t stress out about studying these topics in a great amount of depth. however, there are a lot of topics that fall into this category, including (but not limited to): statistics, probability, sequences, limits, vectors, and matrices.<\/p>\n

it\u2019s pretty enlightening to see how all these different math concepts play with one another. try and find links of your own and you\u2019ll get a better understanding of how numbers behave. and it gives me an excuse to use this gif.
