Maths bits and pieces

Quadratic sequences and the nth term formula
A systematic exploration using algebraic notation.
Special angle values
Work out the exact values of the sine, cosine and tangent for 30°, 45° and 60° using Pythagoras' result and the trig ratios. I've used a limit based argument to justify the values for angles of 0° and 90°.
