Question

Explain the procedure of tracing a curve in polar coordinates.

Answer 1

Following is the procedure of tracing curve in polar coordinates : 

1) Find out weather the curve is symmetric on a line or a point.
2) If the equation of the curve remains unaltered when y is replaced by -y and the curve is an even function of y.
3) If the equations of the curve is such that the powers of both x and y are even everywhere then the curve is symmetrical.
