1. Graphs

   • y=mx+c
     • m=gradient
       • -m will make the graph slope down \
       • +m will make the graph slope up /
     • c=y-intercept

2. speed = distance / time

   • time = distance / speed
   • distance = time x speed

3. nth term

   • linear
     • 4, 10, 16, 22, 28
       • next 2...
         • 34, 40
       • 6n - 2
         • number in front of n is the difference between each number and the second part comes from taking (...)n away from the first term
   • quadratic
     • 2, 8, 18, 32, 50
       • +6 +10 +14 +18
         • +4 +4 +4

4. Pi π

   • 3.14159265359

5. Area

   • rectangle
     • length x width
   • circle
     • πr²
     • circumference = πd
   • trapezium
     • 1/2 (a+b) h

6. Volume

   • prism
     • area of cross-section x length
   • sphere
     • 4/3πr³
   • cone
     • 1/3πr³

7. Surface Area

   • sphere
     • 4πr²
   • cone (curvedSA)
