Can you work out which processes are represented by the graphs?
Can you make sense of the three methods to work out what fraction of the total area is shaded?
Show that if you add 1 to the product of four consecutive numbers the answer is ALWAYS a perfect square.
This is a beautiful result involving a parabola and parallels.
There are many different methods to solve this geometrical problem - how many can you find?
A circle is inscribed in an equilateral triangle. Smaller circles touch it and the sides of the triangle, the process continuing indefinitely. What is the sum of the areas of all the circles?
Do you have enough information to work out the area of the shaded quadrilateral?
Given any three non intersecting circles in the plane find another circle or straight line which cuts all three circles orthogonally.
Stick some cubes together to make a cuboid. Find two of the angles by as many different methods as you can devise.
Draw graphs of the sine and modulus functions and explain the humps.
