#### Explanation:

Starting from the equations of passage from cartesian (rectangular) to polar coordinates

we can replace them inside the given equation and get

that describes our function for

As long as the sign in front of the root is concerned, we have to consider that, according to its defintion

As a matter of fact the polar function describing the given function is the one with the plus sign linking the two terms at the numerator

for

Assuming that intended equation is

#### Explanation:

radius 4.

Let O be the pole and

OC=CP=4 and, easily, #anglePOC=angleCOP-pi/2-theta.angle

OCP=2theta#.

It is immediate from the isosceles

However, the following method befits any circle, with given center

and radius.

So,

This is simply,

Perhaps, some readers might not like this answer, because I have

not used

relatively a short method, for this problem. I agree. Yet, what I did

was for vector orientation

Assuming the equation was
