EZ Graph - Secant Function, -360 to 360 degrees

Click the 'Draw graph' button in the lower left corner of the EZ Graph app. Explanation below.

Here is the conventional notation for this secant function and the computer language type of notation used with EZ Graph:


f1(x) = sec(x) translates to EZ Graph as f1(x) = 1/cos(x)


Since EZ Graph has no built in secant function (most graphic calculators do not), we substitute the reciprocal of the cosine function (1/cos(x)) for the secant function (sec(x)).
