I need help with this question please. I do not understand how to do it.

Given the following function, determine the interval for the principal cycle. Then for the principal cycle, determine the equations of the vertical asymptotes, the coordinates of the center point, and the coordinates of the halfway points. Sketch the graph. y = cot (2x +1c) The interval of the principal cycle is E. (Type your answer in interval notation. Simplify your answer. Type an exact answer, using at as needed. Use integers or fractions for any numbers in the expression.)
