### ListInterpolation and extrapolation: order has been reduced,

ListInterpolation does not expect a list of $\{x_i, y_i\}$ values. The way you are using it, Mathematica interprets it as a 2D array, and in one dimension you have ...

### 2D cross-section of ParametricPlot3D

We may set the z component to a given value and then solve for e.g.u. Then we have u[v]. This then defines a line. The problem here is, that the solution is multivalued. We therefore create as many ...
