Ok, this is going to sound really dumb but in my school they never went over why things are the way they are but basically just had us memorize stuff, so I have a super basic question on phase shift for trig functions. I don't really logicaly understand why in the equation y= Sin(Bx+C), for example, the phase shift is C/B. To me it seems as though the phase shift should just be C, as you are adding C to every value of x, regardless of what happens to x. I understand that you can get it from taking Bx+c=0 to find where it "starts", which would give you x= -C/B but still can't really convince myself that it makes logical sence, I am sure someone can easily help me understand this more though.
Also, does anyone know any good trig. books or websites that go over "why" instead of just stating what everything is? Thanks alot
