EZ Graph - Cotangent Function, Vertical Translation Variable

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

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


f1(x) = cot(x) + k translates to EZ Graph as f1(x) = (1/tan(x)) + k
f2(x) = cot(x) translates to EZ Graph as f2(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)).
