Answer

2\cos\frac{1}{2}x$:

Morning Omar — let's get this done.

Part (a): Complete the table

To complete the table, we substitute the given $x$ values into the equations $y = 2\cos\frac{1}{2}x$ and $y = 3\sin x$ , rounding each result to one decimal place.

For $y = 2\cos\frac{1}{2}x$ :

$x = 30^\circ: y = 2\cos(15^\circ) = 2(0.9659) \approx 1.9$
$x = 120^\circ: y = 2\cos(60^\circ) = 2(0.5
