What you sketched there is \cos(x - \frac{\pi}{2})

In your sketch, you moved it to the right when you should've moved it to the left

Look at the peak of cos(x) at (0, 1). In your sketch it's moved to the right, to (pi/2, 1). To 'move it', you can just imagine moving the y-axis to a different point and calling it 0.
When it comes to sketching graphs, messing around on desmos.com can be quite helpful to build some intuition.
