Invariant Points FP1 - Please help!Watch
The matrix (3 -2)
..................(2 -1) represents a transformation, T. The inverse of transformation T is W.
i) Find the matrix representing W: Complete
ii) Show that TW=WT=I: Complete
iii) Find the invariant points for the transformation T: Complete, points on the line y=x
Then I get stuck on the next part:
iv) T is a shear. The line of shear is the line of invariant points for the shear. The factor of a shear gives the distance a point is moved as a multiple of its perpendicular distance from the line of shear. What is the factor of the shear T?
Please don't just tell me the answer, I need to know how to get there thank you!
