sin(arcsin1/2+arccos1/3)?sin(arcsin1/2+arccos1/3)?sin(arcsin1/2+arccos1/3)?sin(arcsin1/2+arccos1/3)=

sin(arcsin1/2+arccos1/3)?
sin(arcsin1/2+arccos1/3)?

sin(arcsin1/2+arccos1/3)?
sin(arcsin1/2+arccos1/3)
=sin(arcsin1/2)cos(arccos1/3)+cos(arcsin1/2)sin(arccos1/3)
=1/2*1/3+根号(1-(1/2)^2)*根号(1-(1/3)^2)
=1/6+(根号3)/2*2根号(2)/3
=1/6+(根号6)/3
=(1+2根号6)/6
