Build Identifier: 

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.

The previous example file had a mistake in the description of how to reproduce this bug
Comment 3 Netterfield 2012-04-06 23:25:32 UTC 
The but is triggered by a unary operator acting on eg, sin().

so 

    -sin(x + [b (x44)]) 

triggers the bug but 

    -1*sin(x + [b (x44)]) does not.

Unary minus no longer prevents updating of equations.
