Step 1
The coordinates are ordered pairs with the x value listed first.
The change in the x position is 4 - - 2 = 6
The change in the y position is 7 - 5 = 2
Since the midpoint is halfway between A and B, the change will stay the same, so x is - 2 - 6 = - 8 and y is 5 - 2 = 3

Let I ( f ) = a b f ( x ) d x . The midpoint rule (open Newton-Cotes for n = 0) is I0(f)=(b−a)f(a+b2) I 0 ( f ) = ( b a ) f ( a + b 2 )
Show: For f C 1 ( [ a , b ] ) holds | I ( f ) I 0 ( f ) | ( b a ) 2 4 f

I have a circle with a line that is drawn through it at two points. I have the coordinate for the center of the circle, the two coordinates where it intersects the circle and the radius as well. I want to put the two rectangles around the two pieces from the circle. My question is how can I get the coordinates of the rectangle?
