The graph of the followings will be considered
(a) y = sinѳ, 0◦ ≤ ѳ ≤ 360◦
(b) y = cosѳ, 0◦ ≤ ѳ ≤ 360◦
(c) y = tanѳ, 0◦ ≤ ѳ ≤ 360◦
The graph of y = sinѳ, ѳ◦ ≤ ѳ ≤ 360◦
On the graph sheet, draw a long horizontal axis in the middle. Mark a point 0’, 3cm to the left of the origin 0. With centre 0’ draw a circle of radius 2cm. Draw a vertical axis through 0. Call the horizontal axis ѳ – axis and the vertical axis y–axis.
On the ѳ – axis choose a scale of 2cm to…
