c3 jan 2013 paper (turning points problem)

for q4 part b;

Does the max value occur when the denominator is as small as possible (ie giving the biggest value for p(theta)?

And does this mean if we had a minus sign after the 12 in the denominator instead of a plus, we would want the cosine value to equal 1? instead of -1 as they've done here?


hope I'm making sense, thanks :smile:
