           Summary: Polar plot does not update properly
    Classification: Unclassified

Polar plot does not update properly if there is a negative sign in front of the
trigonometric term.

Reproducible: Always

Steps to Reproduce:
1.Create an index vector.
2.Create and equation for the "x" vaules of a circle in the format
x=k*-sin(x+b) (where x is the index vector created above).
3.Create and equation for the "y" vaules of a circle in the format
y=k*cos(x+b).
4. Create a curve with the "x" equation on the x axis and the "y" equation on
the y axis.
5. Edit the scaler value "b" and only the "x" equation will update.
6. Editing the scaler value "k" will cause both equations to update as
expected.
Actual Results:  
The equation with the negative sign in front of the trigonometric does not
update.

Expected Results:  
Equation should update automatically.

I will upload an example file to the mailing list to reproduce this bug.
