You can use the same equation to generate straight lineswith the Equation Editor. Assuming first that p=0, try this:Ampl(p)=1000Press [Preview] and see the flat line which runs parallel to the X-axis.Now, lets give the line some slope by typing:Ampl(p)=-2*p+2000Press [Preview] and see that the line slopes down. Pay close atten-tion to the convention that is used in this equation. You cannot type:Ampl(p)=-2p+1000, instead use the * (multiply) sign, to avoid a syn-tax error. Now we'll generate a simple sine waveform. Try this:Ampl(p)=sin(10)Press [Preview] and you still get a flat line. The sine of 10 in radiansis correctly shown. You are unable to see the result because the lineon your screen running across the 0 vertical point.REMEMBERThe equation must be a function of a single variable andthat variable must be directly related to the Horizontalaxis Scale setting.Now try this:Ampl(p)=sin(omg*p)Press [Preview] and there is no waveform for now, but press the[Adjust] button and the sine appears. To add amplitude (in verticalpoints) to your waveform, enter:Ampl(p)=6000*sin(omg*p)You should now see a perfect sine waveform with a period of 1000points. If you want to create 10 sine cycles, multiply p by 10. Try this:
