Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is: The point (12,5) is 12 units along, and 5 units up. Solution: First sketch the integration region. We interpret r as the distance from the sun and θ as the planet’s angular bearing, or its direction from a fixed point on the sun. Match the point in polar coordinates with either A, B, C, or D on the graph. Here, is the imaginary unit. Also remember that there are three types of symmetry - y-axis, x-axis, and origin. Extrema, intervals of increase and decrease. For polar coordinates, the point in the plane depends on the angle from the positive x-axis and distance from the origin, while in Cartesian coordinates, the point represents the horizontal and vertical distances from the origin. If you want to work with a linear system, you will have to do variable transformations (much like the creation of$\Phi\$ that appears in the first answer of your linked question).
