I have got some doubts for those qs...unable to solve it....
This is a exam q..i got no answer to this anyone can help advise me?

Given a plane contains two straight lines whose equations are
(1) (x-1/-2) = y-4=z

and (2) (x-2/.3) = (y-1/4) = (z-2/.1)

(a) Are the two straight lines parallel to each other? If the coefficient of x is the same in each case, then the lines must be parallel when written in the form y=mx + C



and another doubt i ahve is how to integrate x(1/x-3)? I dun know why it's x-3ln(x-3)...it's bit confusing here...pls advise me soon cos i'm having exam this week...thanks alot
