Question

If you could only plot 5 points to graph y=sinx, which points would you choose? How would you connect these points? Please explain

If you could only plot 5 points to graph y = cosx, which points would you choose? How would you connect these points? Please explain this too!

Answer 1

For both graph I would choose the following points: 0°, 90°, 180°, 270° and 360°. I would connect the points (in both cases) with an smooth arc.

Explanation:

x sin(x) cos(x)

0° 0 1

90° 1 0

180° 0 -1

270° -1 0

360° 0 1
