Verify the following: (-5) + [(-32) + (-2)] = [(-5) + (-32)] + (-2)

If the coordinate of one end of a diameter of a circle is (3,4) and the coordinates of its centre is (-3,2) then the coordinate of the other end of the diameter is .

Three vertices of a rectangle are (3,2),(-4,2) and (-4,5). Plot the points and find the coordinates of the fourth vertex.

The vertices of a triangle are (0,0), (x ,cosx), and (sin^3x ,0),w h e r e0ltxltpi/2 the maximum area for such a triangle in sq. units is (a) (3sqrt(3))/(32) (b) (sqrt(3)/32) (c) 4/32 (d) (6sqrt(3)) /(32)
