Unit 5: Conics Feb. 3, 2012

What is Conics? This is the short term for conic sections. -Conic Sections include circles, parabolas, ellipses, and hyperbolas

Conic Sections are used to describe all of the possible ways a plane and a double right cone can intersect.

Conic Sections in the Real World

CONICS SECTIONS: CIRCLES Notes

Circles

Write the following information in standard form

Pick up a warm up from the front and begin! Feb. 6, 2012

1 st of Conics Sections: Circles 1.Write down everything you know about the given Circle.

2.Write the standard form of a circle with a radius of 4 and a center at the origin.

3.Write the standard form of the equation of a circle that is tangent to the y-axis and has a center at (-5, 4).

4. Write the standard form of the equation of a circle that has its center at (7, -2) and passes through the point (12, 4).

Find the center of the circle and the radius of the following.

CONICS: DAY 2 Feb. 7, 2012

Write the equation of the circle in standard form. Then identify the center and radius.
