Reflection: Lesson Planning Graphing the nonsinusoidal trigonometric functions Day 1 of 2 - Section 4: Closure


My goal in graphing with paper and pencil is not to make the students advanced at this skill.  With technology today doing a lot of paper pencil graphs seems to be too much.  Students need to understand how the graphs look and how the transformations work.  By graphing a few functions the students are better able to analyze graphs and information.

After this unit most students will be able to explain the shape of the graph and the relationship with the key features such as midline, asymptotes, maximums and minimums. 

When the functions are discussed in later units students should be able to sketch a quick graph maybe not to scale by doing the pencil paper if students need a more complicated graph they can use the online tools we used for this unit.
