Distant/Time Graphs

Axis:
x = time
y = distance

Straight Line:
up or down = constant speed

Horizontal Line:
no movement

Gradient:
speed

hope this helps  ;)

is there a metod to find a matrix for rotaton or reflection ode than  simultaneous??????

the matrix for reflection in line y=x is 0 1
                                                  1 0

the matrix for refection in line y=-x is 0 -1
                                                  -1 0

the matrix for clockwise rotation of 90 degrees about the origin is 0 1
                                                                                       -1 0

the matrix for anticlockwise rotation of 90 degrees about the origin is 0 -1
                                                                                             1  0

and u can use the formula method instead of the simultaneous method
