Linear Relationships
Answer
Distance
√(x2-x1)^2 + (y2-y1)^2
General form
0 = ax +by + c
Point gradient
y - y1 = m(x - x1)
Gradient Intercept
y = mx+c
Trigonometry
Answer
Area of triangle
A = 1/2absinC
Sine Rule
a/sin A = b/sinB
Cosine Rule
c^2 - a^2 + b^2 -2ab cosC
Cosine Rule (angles)
cosC = a^2 + b^2 - c^2/2ab
