The equation of a line in parametric form is given by:

A line passing through the points A (-2 , -1 , 5) and B ( 1, 3 , -1) ,find the equation of the line in parametric form. Also, write the equation in non - parametric form.

Distance or parametric form

Given the vector equation of a line as vecr=(2hati-hatj+3hatk)+t(hati-hatj-hatk) find the direction cosines of the line. Find also the equation of the line in non parametric form and in cartesian form.
