In much the same way as you use rectangular coordinates.
With Cartesian or rectangular coordinates, you start from the origin and move a distance of x in the horizontal direction and then a distance of y in the vertical direction.
Using polar coordinates, you start from the origin along a ray inclined at an angle theta with the positive horizontal axis (clockwise from Eastwards), and you go a distance r along that ray.
In all but degenerate cases the Cartesian coordinates of (r, theta) are
x = r*cos(theta) and y = r*sin(theta)
while, conversely,
r = sqrt(x2 + y2) and theta = arctan(y/x).

What is graphing method?
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.

How do you convert polar to rectangular coordinates?
If the polar coordinates of a point P are (r,a) then the rectangular coordinates of P are x = rcos(a) and y = rsin(a).
What are 2 polar coordinates for the point 2 0?
The point whose Cartesian coordinates are (2, 0) has the polar coordinates R = 2, Θ = 0 .
Why is it important to start at the origin when you are graphing points?
It is important for beginners because the coordinates of the graphing points are measured from the origin. More expert users don't need to do so.
