Entering and Evaluating Equations
Th
e next equation also obeys the syntax rules. This equation uses the inverse
function,  , instead of the fractional form,    . Notice that
the SIN function is "nested" inside the INV function. (INV is typed by

.)

Example: Area of a Polygon.
The equation for area of a regular polygon with n sides of length d is:
Area =
