sinewave. So what's wrong? Well, if you'll give it a little amplitude it
might help so, do it now exactly as follows:
Amplitude(p)=8000*sin(omg*p)
There you go. You should now see a perfect sine waveform with a
period of 1000 points. This is because you have asked the Equation
Editor to compute the sine along p points (“p” is the equation
variable, remember?). If you want to create 10 sine waveforms, you
should multiply p by 10. Try this:
Amplitude(p)=8000*sin(omg*p*10)
Equation Examples
So far, you have learned how to create two simple waveforms:
straight lines and trigonometric functions. Let’s see if we can
combine these waveforms to something more interesting. Take the
straight line equation and add it to the sinewave equation:
Amplitude(p)=12000*sin(omg*p*l0)-8*p+4000
Press [Preview]. Your screen should look like Figure 4-37.
Now let’s try to modulate two sine waves with different periods and
different start phase. Type this:
Amplitude(p)=
12000*sin(omg*p)*cos(omg*p*30)
Press [Preview]. Your screen should look like Figure 4-38.
