Solved Examples - The Plane - II
sir... in question no.11 -> we considered the dr's from the intercept form.. is that right?...

We haven't considered dr's in this question. You can solve this question either by using the intercept form or the normal form.
we considered dr's that's why we got the equation 2u+6v+6w=0... isnt it?

Oh yes! u,v,w are the dr's of the normal to the plane. I'm sorry I didn't get you in the beginning.
that's my doubt sir... how we can consider u,v,w as dr's because that was the intercept form...

Supposing we have the equation of a plane in the intercept form as x/a + y/b + z/c = 1. In this, 1/a, 1/b and 1/c are the dr's of the normal to the plane. So all the different forms in which we can write the equation of a plane are related to each other and are not independent. We can easily convert from one form to another.
Thank you sir :)
