Hi,

In my calculus book,I found this vector form of line equation in space (bold means vector):

Given point (x1,x2,x3) lies on line L &

Now, my question if I plug any number for t, then result will be vector <x1,x2,x3> + <at,bt,ct> which is a vector not the whole line.!

In otherwords, what am supposed to get when I plug in a number for t? Am getting a vector which partial of the straight line not the line itself. is this right?

**v**=<a,b,c>, then equation of line is :**r**= <x1,x2,x3> + t <a,b,c> with t any number.Now, my question if I plug any number for t, then result will be vector <x1,x2,x3> + <at,bt,ct> which is a vector not the whole line.!
