Name your file with the following naming convention: last name, first name, Tech C Written components should contain articulate thoughts, acceptable grammar, and should be easy to follow. Quadric Surfaces A quadric surface is any 3D surface described by a quadratic equation in three variables: ax 2 + by 2 + cz 2 + dxy + eyz + fxz + gx + hy + jz + k = 0 . Spheres Standard form equation: (x – x0 )2 + ( y – y0 )2 + (z – z 0 )2 = r 2 Use GeoGebra to generate a slider-model for the standard form equation of a sphere. What do each of the constants control? Be specific and use correct vocabulary. (x – x 0 )2 + (y – y0 )2 + (z – z 0 )2 =1 2 2 2 bx by bz Use GeoGebra to generate a slider-model for the standard form equation of an ellipsoid.
