Look at where the peak is. So, the greatest number of hours of sunlight would be around 180.
40 is the answer if your asking for the second angle
Recall that 2sin(x) cos(x) is actually equal to sin(2x).
We can prove this by expanding sin(2x) to sin(x + x).
sin(x + x) = sin(x) cos(x) + cos(x) sin(x) = 2sinxcosx
Thus, 2sin(x/2)cos(x/2) can be rewritten in the form:
sin(2x/2), and this simplifies down to sinx.
This is one example of a trinomial with a leading coefficient of 3 and a constant term of -5
