Question

What is a 4rth dimensional figure ? How can we visualise them ?

Answer 1

The concept of a 4D figure is a mathematical extension of the concept of a 3D figure. In case of a 4D figure, apart from x, y and z axes, there is a fourth axes say w axis and each point is represented as a 4 tuple, i.e. (x, y, z, w). Such a figure cannot be visualized since the concept of a 4D figure is hypothetical and not realistic.
