Hi,
I have a small question about Datatype. I define a type coordinate as follow:
Datatype `coordinate = <|
x_axis: real;
y_axis: real;
z_axis: real |>`;
it derived and stored some relevant theorems, like
coordinate_component_equality, now I want to use this theorem, I tried to call
it by coordinate_component_equality or
scratchTheory.coordinate_component_equality, but failed.I queried HOL handbooks
and still don't know how to call it, could anyone tell me how to call it?
Regards,
Liu------------------------------------------------------------------------------
