Calculus 3: Ch 2.2 Planes in 3-D Equation (8 of 22) Is the Line Parallel to the Given Plane? Ex. 1

[@arasitininadamar8179]

Thank you so much this helps me for my linear algebra class

[@MichelvanBiezen]

Glad the videos are helpful.

[@MagloireEpo]

Thanks professor for the accurate explanation 👍

[@MichelvanBiezen]

You are welcome

[@darshikabhayani307]

error at 4:42. Should have said parallel to plane

[@reinhartlogronio9786]

thanks for pointing that out

[@Quasifinance]

No there error was throughout the video. At 4:42 he said the right thing.... right?

[@manjumanl222]

Sir, would you mind More on Fourier Transforme subject.

[@MichelvanBiezen]

We are covering a lot of topics. Eventually we will get them all done.

[@mwilamwamba1787]

So does the 12 affect anything on the second vector?

[@MichelvanBiezen]

It is part of the equation of the line. If that number was a different number you would have a different line and a different equation.

[@MichelvanBiezen]

Thank you. We think so too.

[@laraibzia3584]

Thanku sir

[@MichelvanBiezen]

Glad we were able to help.

Your lecture ends with the statement that “since the dot product is not zero, the line is not perpendicular to the plane”. Did you mean to say that the line is not parallel to the plane?

[@MichelvanBiezen]

yes, indeed

[@Quasifinance]

@Michel van Biezen no you're both wrong. If not zero then not perpindicular. He was wrong throughout the video up till that point. Dot product = 0 for orthogonal.

[@mehedyhasantanim]

So angle between this line and plane?

[@MichelvanBiezen]

To find the angle set AB cos(theta) = AxBx + AyBy + AzBz and solve for the inverse cosine.

She is a very sweet and gentle dog.
