X intercept:
sin2x+sinx=0
=> sinx(sinx+1)=0
=> sinx=0;sinx=-1
=>x=nπ;x=mπ+(-1)mπ2
=> x=0,Ï€,2Ï€.. ; -Ï€/2,Ï€/2,5Ï€/2...
f(x)=sin2x+sinx
f'(x)=2sinxcosx+cosx
f'(x)=0 => cosx(2sinx+1)=0
=> cosx=0 ; sinx=-1/2
=>x=(2k+1)π2 ; x=lπ+(-1)lπ6
f"(x)=-2sin2xcosx+2cos2x-sinx
Can anyone finsih it now ??

at 3Ï€/2 and similar intervals..graph wont be sharp..it will be smooth..just touching..
1@eureka ....i wanted it to be smooth
but i am using laptop so my figure can not be perfect as i have no mouse.........i had to use the curve operator in ms paint
