Class methods

cube_root(x : Number)

Source

derivative(t : Float64, p1 : Number, p2 : Number, p3 : Number, p4 : Number)

The derivative represents the rate of change of the interpolation at t

Source

extrema(p1 : Number, p2 : Number, p3 : Number, p4 : Number, &)

Find the values that lie at the extrema of the function, i.e. where the rate of change is 0 these points are typically at the edges of a 2d curve

Source

interpolate(t : Float64, p1 : Number, p2 : Number, p3 : Number, p4 : Number)

Find the value at t along the curve (between 0.0 and 1.0)

Source

roots(p1 : Number, p2 : Number, p3 : Number, p4 : Number, &)

Solves roots so that t = 0
