sin30°cos60°+cos30°sin60°
=1/2×1/2+root3/2×root3/2
=1/4+3/4
=1+3/4
=4/4
=1
so it is equal to sin90°

sin 30×cos 60+cos 30×sin 60=(1/2)×(1/2)+(√3/2)×(√3/2)
                                               =(1/4)+(3/4)
                                               =4/4
                                               =1
                                               =sin 90
