Sorry about the way its laid out. your right that's what i have done i put r=i+j+A(2k-j) into r . (i+j) = 4 which gives me i+j+A(2k-j) . (i+j) = 4 I tried writing this in vectorial format but don't khow how to get the brackets to wrap i,j,k on this website. If you can help with...

Intersection of line and plane! Homework Statement Intersection of line and plane! Okay i to find the common points of line and plane Question r=i+j+A(2k-j) and r . (i+j) = 4 Homework Equations I heard that it is easier to use the vector equation in the form r . n = p The...

I can see what you mean. I wrote the vectorial notation below. Since we are writing it in this way we will have to change the x and y before parallel vector into other letter e.g. a and b. So i wrote the Vectorial notation as it should be below r:⎡⎣xyz⎤⎦=⎡⎣111⎤⎦+a⋅⎡⎣01−3⎤⎦...

HELP! Intersection of two lines (VECTORS) Homework Statement Find the common point of the lines r=i+j+k+x(j-3k) and r=i+y(k-j) Homework Equations The Attempt at a Solution If the lines intersect then there are numbers x and y such that i+j+k+x(j-3k)=i+y(k-j) The two...
