AII.5 and *AII.4 - Solving Non-Linear Systems

AII.5    The student will solve nonlinear systems of equations, including linear-quadratic and quadratic-quadratic, algebraically and graphically. Graphing calculators will be used as a tool to visualize graphs and predict the number of solutions.

AII.4  The student will solve systems of linear-quadratic and quadratic-quadratic equations, algebraically and graphically.

BIG IDEAS

  • I can create telescope and wide-angle camera lenses, reconstruct traffic accidents for investigation, monitor aircraft flight patterns as an air traffic controller, analyze crimes for police officers, and work as a seismologist or geologist.
  • I will be able to solve systems involving linear and quadratic equations, by quadratic equations only by graphing, algebraically, and by using a calculator to visualize the solution.


UNDERSTANDING THE STANDARD

  • Solutions of a nonlinear system of equations are numerical values that satisfy every equation in the system.
  • The coordinates of points of intersection in any system of equations are solutions to the system.
  • Real-world problems can be interpreted, represented, and solved using systems of equations.

·  Quadratic equations included in this standard will only include those that can be represented as parabolas of the form  where .

·  Solutions of a system of equations are numerical values that satisfy every equation in the system.
