▪ The distributive law : a(b + c) = ab + ac
▪ Factoring out a term :
▪ Laws of exponents ( a > 0 ):
▪ Factoring sums & differences of powers :
▪ Absolute values :
▪ The Binomial Theorem :
etc. ( coefficients come from Pascal’s triangle)
▪ The Quadratic Formula : if
then
Basic trigonometry
▪ Angles will always be measured in radians, with positive
meaning counterclockwise.
2π radians is a full circle , so you can convert degrees to radians via
multiplying by 2π/360 .
▪ The three basic trig functions (remember, down and left
are negative !):
▪ Be able to find evaluate trig functions of the “nice
angles”
▪ Trigonometric identities:
| ▫ Pythagorean: |
 |
| ▫ Sum/difference: |
 |
