• Certain functions can be graphed easily using built-in function graphs.
• You can draw graphs of the following built-in scientific functions.

- Input for x and
θ
variables is not required for a built-in function.
- When inputting a built-in function, other operators or values cannot be input.
• Graphing a Parametric Function
Your calculator can graph a parametric function represented by (X, Y) = (f(T), g(T)).
Example To graph using the function parameters below
x = 7cosT − 2cos3.5T y = 7sinT − 2sin3.5T
Use the following V-Window settings.
Xmin = −20, Xmax = 20, Xscale = 5
Ymin = −12, Ymax = 12, Yscale = 5
