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).

Neither of your functions have a well-defined gradient at (0,0)
