  • Develop and assign class exercises that build the students abilities to solve systems of equations and inequalities, and graph functions and relations in rectangular coordinates and polar coordinates.
  • Design class handouts on the unit circle and basic trigonometric graphs, and applying transformation to the graphs of functions and relations for both visual and verbal learning styles.
  • Create flipped classes that transfer instruction and lecture activities accomplished by the student before the class meeting.
