##### Age 16 to 18 Challenge Level:

How many eggs should a bird lay to maximise the number of chicks
that will hatch? An introduction to optimisation.

##### Age 16 to 18 Challenge Level:

Find all the turning points of y=x^{1/x} for x>0 and decide

##### Age 16 to 18 Challenge Level:

Find the relationship between the locations of points of inflection, maxima and minima of functions.

##### Age 16 to 18 Challenge Level:

A point moves on a line segment. A function depends on the position
of the point. Where do you expect the point to be for a minimum of
this function to occur.
