3. Input the polar coordinate expression (
4. Press w to draw the graph.
• You can draw graphs of the following built-in scientific functions.
• View Window settings are made automatically for built-in graphs.

= 7 cos T – 2 cos 3.5T
y
= 7 sin T – 2 sin 3.5T
Use the following View Window parameters.
