If a smooth curve C is given by parametric equations {eq}x=x(t), y=y(t), z=z(t) {/eq}, then the tangent vectors of the curve is given by the vector functions {eq}\left<(x'(t), y'(t), z'(t)\right> {/eq}. The tangent li...
The formula for this addition is thus the same as for addition of functions, (V+W)(p)=V(p)+W(p). This scheme occurs over and over again. We shall call it the pointwise principle: If a certain operation can be performed on the values of two functions at each point, then that ...
