What is the name of the shape graphed by the function r 2 theta?
The name of the shape graphed by the function r ^ 2 = 9 cos (2 theta) is called the “lemniscate”. A lemniscate is a plane curve with a feature shape which consists of two loops that meet at a central point. The curve is also sometimes called as the lemniscate of Bernoulli.

What is the graph of 1 cos theta?
We are multiplying the whole function by a negative, so this corresponds to reflecting the graph of cos(x) over the x-axis. We now have the graph of -cos(x). The next thing we do to 1 – cos(x) is add 1. This corresponds to a vertical shift.

What is cos theta?
The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse. (Image will be uploaded soon) In the given right angle triangle A is an adjacent side, O is perpendicular and H represents the hypotenuse. Cos θ = Adjacent/Hypotenuse. Here θ represents the angle of a triangle.

What is a cardioid shape?
A cardioid (from the Greek καρδία “heart”) is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius. Named for its heart-like form, it is shaped more like the outline of the cross section of a round apple without the stalk.

What is a Limacon graph?
In geometry, a limaçon or limacon /ˈlɪməsɒn/, also known as a limaçon of Pascal, is defined as a roulette formed by the path of a point fixed to a circle when that circle rolls around the outside of a circle of equal radius. A limaçon is a bicircular rational plane algebraic curve of degree 4.

How do you identify a Limacon?
When the value of a is greater than the value of b, the graph is a dimpled limacon. When the value of a is greater than or equal to the value of 2b, the graph is a convex limacon. When the value of a equals the value of b, the graph is a special case of the limacon.

What is polar axis symmetry?
Symmetry in Polar Curves and Equations. Consider a curve generated by the function r=f(θ) in polar coordinates. The curve is symmetric about the polar axis if for every point (r,θ) on the graph, the point (r,−θ) is also on the graph. Similarly, the equation r=f(θ) is unchanged by replacing θ with −θ.
