The Period of Trig Functs {tan(x) or cot(x)}

Select each function one at a time. Change the value of the B slider, the length of the period will be calculated. State the domain and range of each. State the length of the period for each. Which function the inverse of the tangent? cotangent? Can you state the domain for the inverse of each function?
This applet can be used by teachers in a demonstration mode in the classroom or teachers can have students load it on their own computers with a worksheet to be complete for a grade.
