int sec x ln(sec x+tan x)dx=

The solution of the differential equation cos y log (sec x + tan x)dx=cos x log(sec y + tan y)dy is

int (sec x dx)/(log (sec x +tan x)) =

The solution of the differential equation cos y log(sec x+tan x)dx=cos x log(sec y+tan y)dy is (a) sec^(2)x+sec^(2)y=c(b)sec x+sec y=c(c)sec x-sec y=c(d)Non of these

If y=(sin x)^(tan x)+(cos x)^(sec x), find (dy)/(dx)

Evaluate: (i) int(sec x)/(log(sec x+tan x)dx) (ii) int(cos ecx)/((log tan x)/(2))dx
