YOU NEED TO KNOW: that the cosine and sine functions for ALL ANGLES are given by the coordinates of points on the UNIT CIRCLE. The x-coordinates of points on the unit circle give the cosine of the angle between the x-axis and the radius measured anti-clockwise […]
How could I make graph 2 from graph 1? Can you work out the equation of graph 2?
Graph 3 has equation y=sin2x. […]

Comparing investments: there are six investments. Find all the representations (description, formula, graph and table of values) of a single investment. After this, work out which statement fits with which investment.
The teacher leads a very short discussion about the different types of investments, reminding the learners about simple and compound interest. He or […]
