Maximum/Minimum value of trigonometry function
This is a common CIE A levels P1 paper question, but I seem to have forgotten how to do it:
Find the maximum value and the minimum value of
at the least positive value of x at which it occurs.
I understand doing 11-5cos(x/2-45) as being
and so on... but how do I do this if there is a fraction?
Any help would be appreciated, thank you in advance!

As both denominators are always positive you don't have to consider negative values. With
the denominator and numerator positive, a fraction with a constant numerator is at a maximum
where the denominator is smallest and at a minimum where the denominator is largest.
