Set cos(kx-wt) = cos(kx)*cos(wt) and wrestle with the
trig identities until you alleviate your ignorance.

Cecil,

There are an infinite number of different functions one could write to
describe an infinite number of different possible wave shapes. And
none of them would necessarily be mathematically equivalent to
another. But when you write the equation for the superposition of
traveling waves and claim that resultant standing wave is a different
kind of electromagnetic wave, that is a misguided point of view. The
equation for a standing wave is simply a different way of writing the
sum of two traveling waves. Being that there is only one kind to
chose from, there cannot be a different kind of electromagnetic wave.
Is it impossible for you to acknowledge this simple point in a
gentlemanly fashion?

You are extremely wrong and ignorant of mathematics.

Any 'extreme wrongness' notwithstanding, what I don't know about
mathematics could fill a book. On the other hand, you almost
inevitably end up lying and turning technical discussions into
personal attacks. Ask anyone.
