problem 1:
a) Prove the commutative property of two successive rotations in 2-D graphics.
b) Describe in brief about the transformations between coordinate systems.
problem 2:
a) Give the transformation matrix to rotate a point about an arbitrary point.
b) Show that the transformation matrix for a reflection about the line y = - x is equivalent to a reflection relative to the y-axis followed by a counterclockwise rotation of 90^{0}.
problem 3:
a) Prove that a uniform scaling (sx = sy) and a rotation form a commutative pair of operations, but that, in general, scaling and rotation are not commutative.
b) Derive the transformation matrix for rotation about origin.
problem 4: Show that the transformation matrix for a reaction about the line y = x is equivalent to a reflection relative to the x - axis followed by a counter clockwise rotation of 90^{0}.
problem 5:
a) Find out the normalization transformation that uses a circle of radius five units and center at (1,1) as a window and a circle with radius and center at (1/2; 1/2) as a view port.
