the question is: Find the matrix for the transformation which first reflects across the main diagonal, then projects onto the line 2y+3^(1/2)=0 and then reflects about the line 3^(1/2)y=2x.
am i supposed to start by finding the reflection across the main diagonal then multiplying it by the projected first line then multiplying that by the reflected second line?
also, does anyone know how to reflect across the main diagonal in terms such as T(x,y) = (? , ?)o
help is appreciated
