Hi, what do you want to do?
Khan Academy
Identifying a Hyperbola From an Equation, Conic Sections, Algebra II
In this video, Sal shows again how to write an equation of a conic section in standard form and identify the conic section it represents. This time, his example is of a hyperbola (not centered at the origin), which he also graphs.
Khan Academy
Identifying an Ellipse From Equation, Conic Sections, Algebra II
After watching this video, you should be able to write an equation for a conic section in standard form and identify the conic section from its equation. In an example problem, Sal reviews how to complete the square and graph an ellipse...
Khan Academy
Identifying Circles and Parabolas from Equations, Conic Sections, Algebra II
This is the last of three well-done videos on identifying and graphing conic sections from an equation. Here, Sal shows how to graph a circle not centered at the origin and a parabola that opens downward.
