I tried to do this but I don't get the answer as in the book...
A line passes through point (0,4). Its first direction angle is 60°, meaning alpha is 60°.
I found that the second direction angles are 30° and 150° that's is beta is 30° and 150°. But what are the parametric equations of the line for each set of direction angles?
Thx any help appreciated
