Consider the function \(f\colon y =\sin \left (\frac{x}
{2} + \frac{\pi }
{2}\right )\).
In the following list identify the function which has the same graph as the graph of the
function \(f\).
\(g\colon y =\cos \frac{x}
{2} \)
\(k\colon y =\cos \left (\frac{x}
{2} + \frac{\pi }
{2}\right )\)
\(b\colon y =\cos \left (\frac{x}
{2} - \frac{\pi }
{2}\right )\)
\(h\colon y =\cos \left (\frac{x}
{2} -\pi \right )\)
\(m\colon y =\cos 2x\)
