求不定积分∫sin(x/2)dx求不定积分∫sin(x/2)dx求不定积分∫sin(x/2)dx∫sin(x/2)dx=2∫sin(x/2)d(x/2)=-2cos(x/2)+C∫sin(x/2)dx

求不定积分∫sin(x/2)dx
求不定积分∫sin(x/2)dx

求不定积分∫sin(x/2)dx
∫sin(x/2)dx
=2∫sin(x/2)d(x/2)
=-2cos(x/2)+C

∫sin(x/2)dx ===2∫sin(x/2)d(x/2)
==2{-cos(x/2)}+c==-2cos(x/2)+c

∫sin(x/2)dx =2*∫sin(x/2)dx/2=-4cos(x/2)+c
