Solution (By Examveda Team)
$$\eqalign{
& {\text{tan}}\theta + {\text{cot}}\theta = 2 \cr
& {\text{Put }}\theta = {45^ \circ } \cr
& 1 + 1 = 2\left( {{\text{matched}}} \right) \cr
& {\text{So, }}\theta = {45^ \circ } \cr
& \Rightarrow {\text{ta}}{{\text{n}}^{100}}{45^ \circ } + {\text{co}}{{\text{t}}^{100}}{45^ \circ } \cr
& \Rightarrow {1^{100}} + {1^{100}} \cr
& \Rightarrow 2 \cr} $$
