The vector and cartesian equations of the line which passes through the point (1,2,3) and is parallel to the vector hati-2hatj+3hatk are

Answer»

`vecr=(hati+2hatj+3hatk)+lambda(hati+2hatj+3hatk),`
`(x-1)/(1)=(y-2)/(2)=(z-3)/(3)`
`BARR=(hati-2hatj+3hatk)+lambda(hati+2hatj+3hatk),`
`(x-1)/(1)=(y+2)/(2)=(z-3)/(3)`
`barr=(hati+2hatj+3hatk)+lambda(hati-2hatj+3hatk),`
`(x-1)/(1)=(y-2)/(-2)=(z-3)/(3)`
`barr=(hati-2hatj+3hatk)+lambda(hati+2hatj+3hatk),`
`(x-1)/(1)=(y-2)/(-2)=(z-3)/(3)`
