Could anyone please help me learn how to determine the period of a polar or trigonometric parametric function? What I mean is, how do I determine the point in which the curve start tracing itself again over? Up to what point do I trace the whole curve? Our professor and math tutors suggest using the Calculor Window and increment the Tetha Max, but that is rather inaccurate if we need the exact bounds to find the Surface Area of a Curve. Thank you for your help.
