• area of triangle: 1/2 bh
• area of parallelogram: bh
• area of trapezium: a + b/2
• circumference of circle: 2πr
• area of circle: πr^2
• volume of prism: area of cross section x length
• volume of cylinder: πr^2h
• pythagoras theorem: a^2 + b^2 = c^2
• trigonometric values: SOH CAH TOA
• cosine rule: a^2 = b^2 + c^2 - 2bc cosA
• area of non right angled triangle: 1/2 abSINC
• f = ma
• speed = distance ÷ time

  time = distance ÷ speed

  distance = speed x time
