Parabola definition, a plane curve formed by the intersection of a right circular cone with a plane parallel to a generator of the cone; the set of points in a plane that are equidistant from a fixed line and a fixed point in Can you identify the antonym of "protagonist," or the opposite of a hero or heroine?
This lesson plan is based on the activity Tremain Nelson uses in the video for Part II of this workshop. Time Allotment: Two 50-minute periods. Subject Matter: Quadratic functions Parabolas. Learning Objectives: Students will be able to: Generate a quadratic function that describes a given parabola by identifying the values of a, h, and k in ...
Focus of a Parabola. The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.. A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.
2. Give examples of parabolas (or 3-D parabolic shapes) in everyday life. 3. Know the names of the parts of the parabola using the geometric and algebraic definitions. 4. Graph a parabola using a chart of points (a table of X & Y values) 5. Know why are parabolas so useful to us (because of the position of the focus in relation to the parabola).
Just as a quadratic equation can map a parabola, the parabola's points can help write a corresponding quadratic equation. With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and write the parabola algebraically.
Identify what's going on. ( and write it down ) Do the shifting and set the vertex ( the starting point ). Pretend you're at (0, 0). Deal with any flips or taller/shorter issues. Label the points to be a polite math geek!
