(sin x)(tan x + cot x) =
sin x(sin x/cos x + cos x/sin x) =
sin x((sin^2 x + cos^2 x)/sin x cos x) =
sin x(1/sin x cos x) =
1/cos x

- Thank You :) 
sin x * (tan x + cot x)

 ------------ Substituting  and  for tan x and cot x, respectively 





 ----- Cancelling sin x in numerator and denominator

 

 ------- Replacing  with 1
