DPlot

Thank you in advance for looking over this question!

I was wondering why I get the error "Syntax Error: Missing Operator Before Variable" when I try to use the F(X,Y1, Y2...) function under "Generate" from the toolbar along the top of Dplot. Specifically, I am trying to find the arcsine and arcosine of a curve already plotted in Dplot.

When I enter ASIN(Y1) for example, I get "Syntax Error: Missing Operator Before Variable." I'm a little confused as to what this means.
Any input would be great.

Have a good day!

Check to see that you have the latest version (2.3.1.8 ). If not, use "Check for Updates" on the Help menu.

If you do already have the latest version then I've overlooked something. In that case please save your plot as a DPlot file and send it to me.

For anybody else viewing this thread, the problem was ASIN(Y1) with Y1 outside the range +/- 1. At some point I probably need to expand on the error messages with more specific explanations.
