Consider the function

f : y = \sin (\frac{x}{2} + \frac{π}{2})

. In the following list identify the function which has the same graph as the graph of the function

f

.

g : y = \cos \frac{x}{2}

k : y = \cos (\frac{x}{2} + \frac{π}{2})

b : y = \cos (\frac{x}{2} - \frac{π}{2})

h : y = \cos (\frac{x}{2} - π)

m : y = \cos 2 x
