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.
