A function f is said to be continuously differentiable if the derivative f'(x) exists and is itself a continuous function. Though the derivative of a differentiable function never has a jump discontinuity, it is possible for the derivative to have an essential discontinuity. For example, the function.
Homogeneous means properties are same on every point. And isotropic means the property is same in all directions. To understand it, see the uniform electric field below-. At every point ,the electric field is having the same magnitude and towards the bottom. So it is homogeneous. But the the electric field in the vertical and horizontal directions are not the sane.
