Click the 'Draw graph' button in the lower left corner of the EZ Graph app. Explanation below.
Here is the conventional notation for these secant functions and the computer language type of notation used with EZ Graph:
f_{1}(x) = (a)sec(x) | f_{1}(x) = a * (1/cos(x)) | |
f_{2}(x) = sec(x) | f_{2}(x) = 1/cos(x) |
Since EZ Graph has no built in cosecant function (most graphic calculators do not), we substitute the reciprocal of the cosine function (1/cos(x)) for the secant function (sec(x)).
Notice the necessary multiplication operator (*) in the EZ Graph notation between a and (1/cos(x))for f_{1}(x).
