Slider variable value not adjusted correctly
I have only seen this issue happen with the 3d graphing tool. I don't know if it exists in the 2d environment as well.
A summary of the issue: Sometime when I create a slider for a variable, say b, and then later use that variable in a formula, equation, or function, rather than use the value of b assigned by the slider, the applet just treats it as 0.
Here is a way to consistently recreate the issue:
- Define a function of two variables, say f(x,y)=xy.
- Make a slider, say by typing b=2.
- Now attempt to make a curve on the surface that goes in the x direction, at a y=value of b: Curve(t,b,f(t,b),t,-10,10)
- When you hit enter, the curve will use b=0, rather than b=2.
