The graph of $\displaystyle{y}={\sin{{\left(\theta+\frac{\pi}{{2}}\right)}}}\usepackage{cmbright}\Huge\$ is the same as the graph of $\displaystyle{y}={\sin{\theta}}\usepackage{cmbright}\Huge\$ shifted by $\displaystyle\frac{\pi}{{2}}\usepackage{cmbright}\Huge\$ units to the left. The shift will move the hill that had been positioned over the interval $\displaystyle{\left[{0},\pi\right]}\usepackage{cmbright}\Huge\$ to the left so that it will now have the y-axis running through the center. This is also true of the given graph. The rest of the graph will consist of the repeating valley and hill pattern, matching the given graph.
