1.	Find the derivative of the following functions (it is to be understand that a,b,c,d,p,q,r and s are fixed non-zero constants and m and n are integers): `(x)/(1+tanx)`
Answer» Let `y=(x)/(1+tan x)` `rArr (dy)/(dx)=(d)/(dx)[(x)/(1+tanx)]` `=((1+tanx)(d)/(dx)x-x(d)/(dx)(1+tan x))/((1+tanx)^(2))` `=(1+tan x-x sec^(2)x)/((1+tan x)^(2))`
