Median: Middle (put numbers in order and find middle) Mode: “Most” (number that appears the most) Q1: Quartile 1=Median of first half of data Q2: Quartile 2=Median of all data. Q3: Quartile 3=Median of second half of data.
x3 + a3 = (x + a) x2 ax + a2. x3 a3 = (x a) x2 + ax + a2. x2n a2n = (xn an) (xn + an) If n is odd then, xn an = (x a) xn 1 + axn 2. b2 4ac 2a If b2 4ac > 0 – Two real unequal solns. If b2 4ac = 0 – Repeated real solution. If b2 4ac < 0 – Two complex solutions.
This is the college algebra cheat sheet. It is a list of the most important concepts in college algebra, covering everything from basic terms and properties of equality to graphing functions. With it, you will look forward to your algebra assignments and exams.
2 x - 9 y + x 3 y. 2 = sin ( y ) + 11 x . Remember y = y ( x ) here, so products/quotients of x and y will use the product/quotient rule and derivatives of y will use the chain rule. The “trick” is to differentiate as normal and every time you differentiate a y you tack on a y¢ (from the chain rule).
