Curated OER
Lesson #158 Translation and Rotation of Axes
Students practice with the discriminant. In this translation and rotation lesson plan students view a dissectible cone and discuss the discriminant for the second detree equation. They follow the examples from the instructor regarding...
Curated OER
Translation and Rotation of Axes
Students rotate axes to eliminate the xy-term and illustrate the dissectible cone as needed. They also discuss the discriminant for the second degree equation in two variables, as well as the translation of axes and rotation of axes....
