(2) limx=0 x(cosx+sinx/x)/x(x+tanx/x)

limx=0 (cosx+1)/(x+1)=cos0+1/0+1=1+1/1=2

(3) lim x=0 (xcosecx)

limx=0. (0cosec0)=0

LHS=RHS

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(4)limx=0. sinxcosx/3x

=sinxcosx/3x

cosx/x=1. sinx/3=sin(0)/3=0

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(5) limx=0. tan(x/2)/3x

= tanx/2/3x/2x2=

tanx/2/x/2=1

=1/6
