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+sec x)(x-tan x)`
Answer» Let `y=(x+sec x)(x-tanx)` `rArr (dy)/(dx)=(d)/(dx)[(x +sec x)(x-tanx)]` `=(x+sec x)(d)/(dx)(x-tan x)` `+(x-tan x)(d)/(dx)(x+sec x)` `=(x+secx)(1-sec^(2)x)` `+(x-tan x)(1+sec x tan x)`
