Hi,

The plot will be same as the shape of cos(x). Its just that its max value will be A. Its time period will be 4 seconds. Or it will complete one cycle in 4 seconds.

The graph will start from (0, a/root2) for t=0 and will follow the cosine graph than onwards. It will attain 0 at ½ seconds, lowest value -A at 1.5 seconds, And max value, A at 3.5 seconds.
