Pupils are introduced to the four quadrants terminology. They then use the trig graphs ( sin, cos and tan ) to find how the sin, cos and tan of angles between 0 and 360 degrees relate to each other.
Finally there is a set of 12 multiple-choice questions to consolidate their understanding of the relationships
