sin(arccos1/3)=?sin(arccos1/3)=?sin(arccos1/3)=?cos(arccos1/3)=1/3sin(arccos1/3)^2+cos(arccos1/3)^2=
sin(arccos1/3)=?
sin(arccos1/3)=?
sin(arccos1/3)=?
cos(arccos1/3)=1/3
sin(arccos1/3)^2+cos(arccos1/3)^2=1
sin(arccos1/3)^2=1-(1/3)^2=8/9
arccos1/3在[0,Pi/2]之间,sin(arccos1/3)>0
所以sin(arccos1/3)=(2/3)根号2
