This webpage checks how well you understand cotangent curves, i.e. graphs of the trigonometric equation y = a*cot(x+c). The value of |a| is called the amplitude and c is the phase angle. Below is a graph for specific values of a, c. Your aim is to find these values and plot the graph of the same function.
