Vector from point 1 to point 2 is given by:
(-3-2,2-4,2-4) = (-5,-2,-2)
l e n g t h = 5 2 + 2 2 + 2 2 = 33
So unit vector is:
( 5 / 33 , 2 / 33 , 2 / 33 )

Given the vector r(t)=cosT,sinT,ln(cosT) and point (1, 0, 0) find vectors T, N and B at that point.

Vector T is the unit tangent vector, so the derivative r(t) is needed.

Vector N is the normal unit vector, and the equation for it uses the derivative of T(t).

The B vector is the binormal vector, which is a crossproduct of T and N.

Finding the transformation matrix given the transformation
Given the Transformation P ( x 1 , x 2 , x 3 ) = ( x 2 , x 3 ), and I'm supposed to find the transformation matrix A so that A ( x 1 , x 2 , x 3 ) = ( x 2 , x 3 )
How do I do this? I managed to find it for a previous question through trial and error but it took me a while and I need a good mathematical way to do it
