 Author Topic aceandrew Posted - 6 December 2001 19:51  what are basic math equtions on the ACT?(ex. a^2+b^2=c^2) Justsmile90 Posted - 18 January 2006 0:0  um, i haven't taken it yet, but i took a practice on on this website (well actually only 65 questions of it- i didn't have time to do the rest. but that included english, math, and one reading passage's worth of questions) and i got a 96.92% on that whole thing (which is weird, because I'm only in tenth grade)... i think that the ACT is mostly like algebra and geometry, some algebra II, and i saw one question from the first week of precalc, so it's not that bad... nothing too out there... silverstarmaddy Posted - 7 April 2006 23:21  You don't know how luck you are to be a sophomore. Register NOW, you'll benefit from it. When I got to be a junior and everyone told me to take it then, big mistake. I totally couldn't remember the simple formulas, b/c I was in a trig. class and chemistry so it's just overall harder to retain even the simple stuff. nerdvanagirl Posted - 3 April 2009 2:46  The formulas for the area of basic shapes (and circumference of a circle - diameter * pi , et cetera), the angles of parallel lines when cut by a transversal, the distance formula, slope-intercept form and point-slope, the Pythagorean theorem, and the laws of sine and cosine (everything with side-angle-side and sohcahtoa) couldn't hurt. I'd also suggest memorizing the Pythagorean triples (they're ratios) and rules such as, the hypotenuse is always the longest leg, and things like that. Memorize things on probability (including combinations and permutations) and calculating percentages, and laws for exponents (when to add them, when to multiply, et cetera).

I know it seems like a lot, but if you take it slow and try to understand the principles behind it it's much easier to remember, and it's well-worth it to get a great score on the math portion.
