Another example is the set of zeros of the cosine function.

In this case, the directions for minimum W will be those that maximize the directional cosine function.

As explained below, this stems from the boundary conditions implicit in the cosine functions.

It is interesting to note that the inverse cosine function yields two possible values for the argument.

That is where the graph of the cosine function intersects the line .

It's just a a cosine function of whatever figure that is whatever figure X represents.

The major points to note from the solution are the exponential term and the cosine function.

A weighting scheme with cosine function is used.

This hyperbolic cosine function describes the shape of a catenary.

Similarly U is calculated from a cosine function.
