A level trigonometry CAST diagram - Pure mathematics

No more need for CAST diagrams if you hate them as much as me!

Remember these 5 rules with any value you have for trig:
1. Sin(x) = sin(180-x)
2. Cos(x) = cos(360-x)
3. Sin and cos repeat every 360 degrees
4. Tan repeats every 180 degrees
5. Sin(x) = cos(90-x)
