Click the 'Draw graph' button in the lower left corner of the EZ Graph app. Explanation below.
Here is the conventional notation for these cotangent functions and the computer language type of notation used with EZ Graph:
f_{1}(x) = (a)cot(x) | f_{1}(x) = a * (1/tan(x)) | |
f_{2}(x) = cot(x) | f_{2}(x) = 1/tan(x) |
Since EZ Graph does not have a built in cotangent function, we substitute the reciprocal of the tangent function (1/tan(x)) for the cotangent function (cot(x)).
Notice the necessary multiplication operator (*) in the EZ Graph notation between a and (1/tan(x))for f_{1}(x).
