hello,
I'm trying to understand all that stuff about waves being out-of-phase, leading by 180 degrees or lagging by 90 degrees etc.
Although I'm doing quite well really, largely due to a dogged persistence and refusal to give up, there is one thing at least that no matter how much I try, I cannot get the hang of.
That is, I don't know how to tell, when you're looking at a diagram of say 2 waveforms out of phase, WHICH WAVE STARTED FIRST.?
Is there actually a way of telling which wave started first?
By the way, I found that Worksheet provided by this Forum, on drawing a Sine wave by doing the angles of a circle, not only very informative, but also fun to do.
