y=ab^x

Example: log(base 9)27 to.... 9^x=27........ x=3/2

7^3x=20 to log7^3x=log20.... divide both sides by 3log7...... get x=log2­0/3­log­7..... finally use the calculator to end.

Find line of best fit, f(x) is the prediction of that number plugged into formula.

Find AOS first; x=number of AOS

cscx= 1/sinx
secx=1­­/cosx
cotx=1­­/tanx

tanx=s­­in­x­/cosx
cotx=c­­os­x­/sinx
