This is mostly just a definition question.

Explanation:

By definition:
#color(white)("XXX")color(red)(cot(x) = 1/(tan(x)))# and #color(blue)(tan(x)=1/cot(x))#

#L.S. = color(red)(1/(tan(x)))+color(blue)(1/(cot(x)))#

#color(white)("XXX")=color(red)(cot(x)) +color(blue)(tan(x))#

#color(white)("XXX")=color(blue)(tan(x)) + color(red)(cot(x))#

#color(white)("XXX")=R.S.#
