10 graphs of experimental data are given. Can you use a spreadsheet to find algebraic graphs which match them closely, and thus discover the formulae most likely to govern the underlying processes?
Four vehicles travel along a road one afternoon. Can you make sense
of the graphs showing their motion?
What fractions can you find between the square roots of 56 and 58?
Can you hit the target functions using a set of input functions and a little calculus and algebra?
By tossing a coin one of three princes is chosen to be the next
King of Randomia. Does each prince have an equal chance of taking
Can you work out the equations of the trig graphs I used to make my pattern?
Which line graph, equations and physical processes go together?
Draw the graph of a continuous increasing function in the first
quadrant and horizontal and vertical lines through two points. The
areas in your sketch lead to a useful formula for finding
What functions can you make using the function machines RECIPROCAL and PRODUCT and the operator machines DIFF and INT?
2009 was clearly an interesting year! Find out which mathematical
fact about 2009 we found most interesting.
