Ian's Javascript Complex Exponential Series
Exponential /Sine/Cos Calculating Program

This program uses complex maths to calculate trignometric functions using
only + - *(times) and / (divide) arithmetic operations.
(Version 4.1 5/9/16 for drop down menus works ok)

Type the values you want into the form and click the "Plot Selected Complex Trig" button.

The horizontal scale of both the exponential curve and the sine and cos curves is the same
and is controlled by the sine/cos plotting period. There is a connection between the period
of the sine and cos curves and the exponential, which you will understand if you know about
complex exponential series.
(If the period is set too small the curve breaks down as the series sum overflows.)
The vertical scale of the sine and cos curves and the exponential curve is different, and is set in pixels per mathematical unit.
