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.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
