| Question | Answer |
| C1 Arithmetic Series : nth term | Un = a + ( n - 1) d |
| Arithemtic Series : sum | Sn = n/2 ( a + (n-1) d |
| Differentiation | y=x -----> dy/dx (derivative) -----> d2y/dx2 f(x) -----> f'(x) -----> f"(x) 1. power x coefficient 2. power -1 Gives estimate for gradient of tangent |
| Integration | d2y/dx2-----> dy/dx (derivative) -----> y=x f"(x) -----> f'(x) -----> f(x) 1. power +1 2. coefficient/power 3. + C Gives equation of line |
| Arithmetic Series: Sum using last term | Sn = n/2 (a+L) |
