percent to fraction
Give this one a try later!
percent as numerator and 100 as denominator, then simplify
negative exponents...
,Give this one a try later!
CANNOT EXIST, so you must make it into a fraction
how to find domain with a given equation
Give this one a try later!
-if a fraction, set denom. to zero, then solve
-in equation, plug in 0 for x
usually can be a + or - solution
fraction to percent
Give this one a try later!
1) do long division with denom as outside and numerator as inside
2) move decimal over 2 places to make it into a %
do not forget decimal
ORRRR
make denom 100 (multiply num and denom of original fraction by whatever
to get it to 100)
Associative Property

, Changing the grouping of numbers will NOT change the value
ex: (a+b)+c=a+(b+c)

-make denoms the same
-add/subtract numerators
sin, cos, tan

SOHCAHTOA
hypotenuse= always across from largest angle measurement
adjacent= (depending on what angle you're looking for) is always along the
side with the missing angle
opposite= opposite from the angle you're trying to find
