Question #16a39

1 Answer

Oct 10, 2016

See below.

Explanation:

The rotation matrix is

#R=((-1, 0),(0, -1))#

and the reflexion matrix about the #x# axis is

#E = ((1, 0),(0, -1))# so given

#T=DeltaPQR#

then

#T_R = R.T#

and

#T_E = E.T#

Attached a plot showing

#T# in black
#T_R# in red
#T_E# in blue
