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 dont 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, im sure someone can easily help me understand this more though.(adsbygoogle = window.adsbygoogle || []).push({});

Also, does anyone know any good trig. books or websites that go over "why" instead of just stating what everything is? Thanks alot
