see below

Left Side#=(tan theta-sin theta cos theta)/sin^2 theta#

#=(tan theta-cos theta tan theta * cos theta)/sin^2 theta#-->#sin theta = cos theta tan theta#

#=(tan theta-tan theta cos^2 theta)/sin^2 theta#

#=(tan theta(1-cos^2 theta))/sin^2 theta#

#=(tan theta sin^2 theta)/sin^2 theta#

#=tan theta#

#=#Right Side
