Methods Rules

1. The Gradient and The Angle: m = tan θ

2. Parallel, m1=m2

3. Perpendicular, m1 x m2 = -1 OR m1 = -1/m2

4. General Eequation of having a radius of length r, and centre at some point (h,k) is: (x-h)² + (y-k)² = r²

5. Turning format: y= a (x-h)² + k

   • a= Dilation (Narrower/wider)
   • h= Translation (left/right)
   • k= Translation (up/down)

6. The Remainder Theorem: When P(x) is divided by (x-a), then the remainder is R- P(a)

7. When P(x) is divided by (ax+b), then remainder is R=P(-b/a)
