That is what I was thinking as well, Ray and LCKurtz. Thank you all so much for your help with this.

Great! Thank you!

I don't know if this is supposed to be a narrative description or an equation, either. I could not think how to find the equation of the plane given this information. I could find the equation of the line, but not the plane. Wouldn't I need a point outside the plane? Plus, it says "All...

Thanks, Simon. I have checked the arithmetic of n . v and also |n| and |v|, and those are correct. The inverse cosine of course I have to rely on my calculator for. :) I think what you're saying is that since the angle that results here is the angle between n and v, that the angle I found...

Homework Statement Sorry, this should say "Calculus III problem". Describe the region that contains all planes passing through (4, 5, 6) that are parallel to <1, 2, 3>. Homework Equations The Attempt at a Solution I cannot imagine how to answer this. I expect that there are multiple planes...

Homework Statement Find the smallest angle between 3x-2y-4z = 5 and {x = 1 + 2t, y = 3 + 4t, z = 5 + 6t}. Homework Equations 3x-2y-4z=5 is a plane, the other 3 equations constitute a line. The Attempt at a Solution My understanding is that the angle between a plane and a line can...
