This is a really basic calc/physics question.If acceleration is defined as
Acc= Asin(w*t), and I integrate this to get velocity, I get
Vel=(-A/w)*cos(w*t)+C.
If the velocity at t=0 is 0, then C=A/w.
If I then integrate the velocity to get the displacement, I get:
Disp=(-A/w^2)*sin(w*t)+A*t/w+C
If Disp=0 at t=0, then C=0
If I plot this displacement, it is not sinusoidal about x=0 axis. it is always increasing in waves. So, it looks like a sin wave at a 45 degree angle.
Is this right? I was expecting an up and down motion, so a sine wave about x=0.
