Function Pyramids
Age 16 to 18 Challenge Level:
A function pyramid is a structure where each entry in the pyramid is determined by the two entries below it. Can you figure out how the pyramid is generated?
Big, Bigger, Biggest
Age 16 to 18 Challenge Level:
Which is the biggest and which the smallest of $2000^{2002}, 2001^{2001} \text{and } 2002^{2000}$?
How Does Your Function Grow?

What Are Complex Numbers?
Age 16 to 18
This article introduces complex numbers, brings together into one bigger 'picture' some closely related elementary ideas like vectors and the exponential and trigonometric functions and. . . .
Exponential Trend
Age 16 to 18 Challenge Level:
Find all the turning points of y=x^{1/x} for x>0 and decide whether each is a maximum or minimum. Give a sketch of the graph.
Gosh Cosh
Age 16 to 18 Challenge Level:
Explore the hyperbolic functions sinh and cosh using what you know about the exponential function.
Extreme Dissociation
Age 16 to 18 Challenge Level:
In this question we push the pH formula to its theoretical limits.
Complex Sine
Age 16 to 18 Challenge Level:
Solve the equation sin z = 2 for complex z. You only need the formula you are given for sin z in terms of the exponential function, and to solve a quadratic equation and use the logarithmic function.
Blood Buffers
Age 16 to 18 Challenge Level:
Investigate the mathematics behind blood buffers and derive the form of a titration curve.
Harmonically
Age 16 to 18 Challenge Level:
Is it true that a large integer m can be taken such that: 1 + 1/2 + 1/3 + ... +1/m > 100 ?
Power Match
Age 16 to 18 Challenge Level:
Can you locate these values on this interactive logarithmic scale?
Cobalt Decay
Age 16 to 18 Challenge Level:
Investigate the effects of the half-lifes of the isotopes of cobalt on the mass of a mystery lump of the element.
Drug Stabiliser
Age 16 to 18 Challenge Level:
How does the half-life of a drug affect the build up of medication in the body over time?

Age 16 to 18 Challenge Level:
What is the total area of the triangles remaining in the nth stage of constructing a Sierpinski Triangle? Work out the dimension of this fractal.
Infinite Continued Fractions
Age 16 to 18
In this article we are going to look at infinite continued fractions - continued fractions that do not terminate.
Tuning and Ratio
Age 16 to 18 Challenge Level:
Why is the modern piano tuned using an equal tempered scale and what has this got to do with logarithms?
