    Consider the lines & find an equation of a plane [Cal III]

    Yes, you are absolutely right. Having 0 as the coefficient of Z is what scared me. My professor hadn't covered what that meant very well, so I was confused. Thank you very much for your input.

    Consider the lines & find an equation of a plane [Cal III]

    Thank you so much. I think I figured out the error in my way of thinking. For some reason I was thinking of my answer as looking like a cube in R3. But since x + y = 5 is a line in R2, I could just scale the Z value infinitely in either direction in R3, as long as I'm restricted to that line...

    Use vectors and the dot product to prove the midpoint

    Hey, thank you for your reply. I went about it a little differently than I originally posted and was able to prove it. Thanks for mentioning that a vector's magnitude is equal to the square root of that vector dotted by itself. Using that idea, I was able to prove that the distance to every...

    Use vectors and the dot product to prove the midpoint

    Homework Statement [/B] Use vectors and the dot product to prove that the midpoint of the hypotenuse of a right triangle is equidistant to all three vertices. Homework Equations [/B] I know the dot product is A⋅B = |A||B|cosΘ ... or ... A1B1 + A2B2 + A3B3 ... + AnBn I know the...
