Question

True or false: The value of r represents the reference angle when plotting a point in polar coordinates.

Answer 1

This statement is false. The value of r does not represent the reference angle when plotting a point in the polar coordinates. In fact, r represents the distance of an angle because the theta is the one who gets to represent the reference angle. 

Answer 2

Answer with explanation:

The Given Statement is "False": The value of r represents the reference angle when plotting a point in polar coordinates.

"r"→ , Represents distance from origin to the point in two dimensional plane in polar coordinates.

Suppose, Point P in two dimensional plane has coordinates , (x,y) or (-x,y),or (-x,-y) or (x,-y).

If we represent,this point in terms  of polar Coordinates ,then

→r=OP=Distance from Origin to Point P

     $=\sqrt{x^2+y^2}$
