Question 1014289
.
Prove the Identity:
1/ tan x + tan x = sec x csc x 
-------------------------------------


{{{1/tan(x)}}} + {{{tan(x)}}} = {{{1/((sin(x)/cos(x)))}}} + {{{sin(x)/cos(x)}}} = {{{cos(x)/sin(x)}}} + {{{sin(x)/cos(x)}}} = {{{(sin^2(x) + cos^2(x))/(sin(x)*cos(x))}}} = {{{1/(sin(x)*cos(x))}}}.


This is exactly sec(x)*csc(x).
