SUMMARY
The discussion centers on the orthogonality of the derivative of a time-dependent vector function with constant magnitude. Specifically, when considering a vector function r(t) of constant magnitude, the derivative r' is orthogonal to r. This is established by differentiating the equation r^2 = r(t) · r(t), which leads to the conclusion that the time derivative of the magnitude remains constant, thereby confirming the orthogonality.
