A polar curve is simply the resulting graph of a polar equation defined by r and θ. We use polar grids or polar planes to plot the polar curve and this graph is defined by all sets of (r, θ), that satisfy the given polar equation, r = f (θ).

In algebraic geometry, the first polar, or simply polar of an algebraic plane curve C of degree n with respect to a point Q is an algebraic curve of degree n −1 which contains every point of C whose tangent line passes through Q.

A polar curve is a shape constructed using the polar coordinate system. Polar curves are defined by points that are a variable distance from the origin (the pole) depending on the angle measured off the positive x x -axis.

Using parametric equations, x and y values are computed independently and then plotted together. This method allows us to graph an extraordinary range of curves. This section introduces yet another way to plot points in the plane: using polar coordinates.

There are five classic polar curves: cardioids, limaҫons, lemniscates, rose curves, and Archimedes’ spirals. We will briefly touch on the polar formulas for the circle before moving on to the classic curves and their variations.

In a polar coordinate grid, as shown below, there will be a series of circles extending out from the pole (or origin in a rectangular coordinate grid) and five different lines passing through the pole to represent the angles at which the exact values are known for the trigonometric functions.

Sketch polar curves from given equations. Convert equations between rectangular and polar coordinates. Identify symmetry in polar curves and equations. The rectangular coordinate system (or Cartesian plane) provides a means of mapping …
