For this matrice,
[[0.9cos(-30), 0.9cos(60), 2]
[0.9sin(30), 0.9sin(60), 4]
[0, 0, 1]]
What is the rotation (in degrees) and is it clockwise or counterclockwise?



I think it's 30 degrees clockwise...Is that right?

    Prove: (3cosx + 4sinx)^2 + (4cosx - 3sinx)^2=5 ...this is all under the square root sign. I get 9cos^2x + 16sin^2x +16cos^2x + 9sin^2x now i know that sin^2 equals 1-cos^2....so would that be 9cos^2x + 17-cos^2x+16cos^2+ 10cos^2x?
