Both a) y=sin (x+ pi/2) and b) y=-cos(x-pi) has identical graphs.
The +- pi/2 shifts to the LEFT or RIGHT respectively. So the first plot is simply a cosine curve.
The second is a cosine shifted by pi, which gives -cos(x) but we have a negative out front so both (a) and (b) are cosine.

The coefficient of determination is calculated as: 0.520.
<h3>How to Find the Coefficient of Determination?</h3>
The coefficient of determination = the square of the correlation coefficient.
Given the following:
Value of the linear correlation coefficient (r) = -0.721
Therefore, we would have:
The coefficient of determination = (-0.721)²
The coefficient of determination = 0.520
