Parametric equation is the set of equation that defines the qualities as functions of the number of independent variables, also known as parameters. Parametric equation of straight line is the polar representation of a straight line. The parametric form is given as p = rcos(Θ - A). Use our online geometric calculator to calculate the parametric form of straight line on space (x, y and z value) based on direction cosines and point coordinates.

x = x1 + t cos α
y = y1 + t cos β
z = z1 + t cos γ
Where,
cos = Cosine
α, β, γ = Angle
x, y, z = Point Coordinates
x1, y1, z1 = Point Coordinates
t = ParameterIf x, x2, x3 is 1,2,3 and α, β, γ is 3,2,1 and parameter is 5, then
x = 1 + (5 x cos 3)
= 5.99.
y = 2 + (5 x cos 2)
= 6.99.
z = 3 + (5 x cos 1)
= 7.999.
