see below

Left Side:#= sin x/(1-cosx) +(1-cosx)/sinx#

#=(sinx * sinx+(1-cosx)*(1-cos x))/(sinx(1-cosx))#

#=(sin^2 x + 1-2 cos x+cos^2x)/(sinx(1-cosx))#

#=(sin^2x+cos^2x+1-2cosx)/(sinx(1-cosx))#

#=(1+1-2cosx)/(sinx(1-cosx))#

#=(2-2cosx)/(sinx(1-cosx))#

#=(2(1-cosx))/(sinx(1-cosx))#

#=2 1/sinx#

#=2csc x#

#=#Right Side
