Computer packages for differentiating polynomial and trigono-
metric functions

Teaching steps
1. Assist students through discussion to recognize mathematical
softwares such as Maple, MATLAB, and other packages that
are used for differentiating polynomial and trigonometric
functions.

2. Use Examples 8.33 to 8.35 in the Student’s Book to guide
students and assist them in differentiating functions by using
the Maple software.
3. Use Examples 8.36 to 8.38 in the Student’s Book to guide
students and assist them in differentiating functions by using
the MATLAB software.
4. Guide students through discussions to differentiate various
polynomial and trigonometric functions by using Maple and
MATLAB softwares from suggested resources.
