Appendix B. Coordinate Geometry (continued)
objective
to review basic facts of coordinate geometry and conic sections
key ideas and/or vocabulary
regular coordinate system (Cartesian plane), R2
, quadrants, graphing inequalities, distance formula, circles, completing
the square, slope, point-slope form, slope-intercept form, linear function,
intercepts, parallel and perpendicular lines, conic sections (parabolas,
ellipses, hyperbolas)
solved problems - using key ideas
#12,24. finding equations of lines
#26. slope and intercepts
#34,36. sketching graphs of inequalities
#40. finding equation of circle using "completing the square"
#46,52. linear function in application
parabola, basic formula, how do we find the location
of the vertex?, is the parabola opened up or down, sideways?
ellipse, basic formula, how do we locate the center, length
of major and minor axis?
hyperbola, basic formula, what is the point around which the
hyperbola is centered?, what are the asymptotes?, in what direction are
the branches open?
#60. sketching regions bounded by curves (graphing calculator)
