The figure above shows part of the graph of
y=1+2 sin(qxº + pº), XER,
where q and p are positive constants with 0°< p <90°, 0
The graph crosses the y axis at the point A(0,1+13), and the x axis at the points
C(50,0) and D.
The point B is a maximum point on the curve.
(5)
a) Determine the value of q and the value of p.
(5)
b) Find the coordinates of B and D.
