y(x,t)=A sin (kx + ωt - φ) + D ? giving 5 stars?
what is A and what is D in this equation?
I know that A is an amplitude but I don't fully understand it. And for I am not sure either. Thanks in advance, giving 5 stars as always.
Update:I forgot to put D in "And for D I am not sure either"
So basically I need an in depth explanation of A and D in this equation, with some examples if possible. THANKS

A is amplitude, D is just some constant that off sets it. So instead of the wave going from -A to A, it will go from -A+D to A+D. It just moves the sine wave up.
