1) Visit web sites for the few leading information systems consulting the firms. Try to determine the information regarding the approach they utilize in order to develop systems. Specify whether SDLCs are described there? Also state do their sites explain any of the tools?
2) Two triangles a and b have been projected onto the window centered at the origin which is 3 units wide and 2 units high. The projected vertices of a are (0,0),(1.4,1.4),(1.4,0) projected vertices of b are (0.2,0.9),(0.2,-0.9),(-2,0) determine the locations of these vertices after mapping them to the view port whose origin is at lower-left corner and which is 60 pixel wide by 60 pixels high.
