Calculate values for y = ((1)/(2)x).

Here's a complete solution for the problem.

19. Complete the following table for the given functions

Step 1: Calculate values for $y = \sin\left(\frac{1}{2}x\right)$.
We substitute each $x$ value into the function.

• For $x=0$: $y = \sin(0) = 0$
• For $x=\frac{\pi}{2}$: $y = \sin\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2} \approx 0.71$
• For $x=\pi$: $y = \sin\left(\frac{\pi}{2}\right) = 1$
