why vertical tangets of some functions like x ^1/3 are not shown ?
Please post your .ggb file
Please see the attached ggb file...
Define the curve parametrically like this
Curve(t³, t, t, -5, 5)
Ok sir, thank you ...
By why it is not shown if we define it as a function ?
A similar problem occurs in the case of the function abs(x)^2, at (0,0). This function is nothing but x^2, but if we define it as abs(x)^2, tangent disappears at (0,0).
The .ggb file is attached
Neither of your functions have a well-defined gradient at (0,0)
