Circles, Ellipses, Hyperbola

We started by looking at graphing ellipses.

Began by with the equation for a circle of radius = 1. Then saw how coefficients change the shape into an ellipse.

The ‘eccentricity’ in a way measures how different an ellipse is from a circle.

Saw how the center is found as well as the axes. X is connected to horizontal and y is connected to vertical.

Ended by looking at hyperbola and a Friday sheet that included Sigma (summation) notation.
