point to me to where it is? It is my first post to this thread, at level 2, responding directly to Dave. 2. You are saying that A is not a function of time. OK, OF COURSE that changes the appearance of the curve I was using. Still, the total energy expended over one cycle (can be thought of as phase angle - distance, not time), 0 to 2pi radians, is = zero As always, engineering is done by strict language. Look at your own. "Expended" energy is power. Integration of power over time will never result in no power unless no energy was "expended." (It is still valid to integrate and cancel out C ;-)) Over the full cosine power cycle, energy is still conserved, however the model is totally different. The model never changed, the consideration of superposition (partial solutions) may momentarily suspend us, but upon its completion the complete solution resolves to exactly what I've posted. Hence, there is no "missing" power (energy, etc.). Why didn't you mention that A was not a function of time before? Consider the genesis of the formula. It informs us all that this is a point location solution of total illumination from two remote sources. There is no need for me to create a shopping list of all the things this formula is NOT a function of. I am only trying to show conservation of energy which must hold true for any of these power formulas to be correct. And this equation still shows conservation of energy being true, even if A is the phase angle. If it is any different from what is not already in my post, feel free to elaborate. 73's Richard Clark, KB7QHC |
