solving absolute value equations (Equations and equalities)

If |"A" | = b, then A = b and A = -b

(s-t)(x). do you distribute negative? (Functions and Graphs)

YES

cotangent, cosecent, and secent ratios (Trigonometry)

cotangent flips tangent co*s*ecent flips *s*ine secent flips cosine

how to solve a fraction divided by a fraction (Rational Expressions)

multiply by reciprocal!

raising two fractional exponents by a power (Rational Expressions)

note that the 2 doesn't Change

Transformations (Functions and Graphs)

x inside y outside x are reversed order except reflections: x outside, y inside

build the magic Hexagon (Trigonometry)

1. Start with tan(x) = sin(x)/cos(x) quotient identity 2. COtangent is across from tangent 3. COsecent, the other CO, is clockwise to cotangent (csc) 4. Sececnt is clockwise to cosecent.

Greatest common *factor* VS least common *multiple*

factors are smaller numbers than input number multiples are larger numbers than input number

covert radians to degrees and vis versa (Trigonometry)

radians to degrees : radians* *(180/pi) degrees to radians: degrees*(pi/180) note: pi = 180
