Math Placement Exam Study Guide.

Convert radians to degrees - answer✔✔Radians • 180 degrees/pi radians

Convert degrees to radians - answer✔✔Degrees • pi radians/180 degrees

Find radian measure of an angle - answer✔✔Theta=s/r when central angle is given


Arc=r•theta when arc length is given


Radius=s/theta when radius is given

Log bY=X - answer✔✔•when b is greater than Y remember that is m/n


•when b less than Y and no whole number can be raised remember to set exponential equation

Product Property of Logs - answer✔✔LogbXY<-->logbX+logbY

Power Property of Logs - answer✔✔LogbX^r <--> rlogbX

Quotient Property of Logs - answer✔✔Logb(X/Y)<-->logbX-logbY

Canceling a log - answer✔✔Use exponentiation:
2^log2(x^2 +3x)=2^2
(x^2+3x)=2^2

Translation - answer✔✔(x,y)-->(x+2,y-2)
