sin 60.cos 30- cos 60.sin 30 = cos(90-60).cos 30- cos 60.cos(90-30)

                                                = cos 30.cos 30- cos 60.cos 60

                                                = cos^{2} 30 - cos^{2} 60

                                                = (√3/2)^2 - (1/2)^2

                                                = 3/4-1/4

                                                = 1/2

hope it helps..........
