" (viii) "sin x sec^(2)x

e ^ (x) sin x tan x + e ^ (x) sin x + e ^ (x) sin x sec ^ (2) x

Solve the following differential equations. cos x. (dy)/(dx)+y sin x = sec^(2)x

int x sin x sec^(3)xdx

int " log sin x . sec"^(2) " x dx "

int " log sin x . sec"^(2) " x dx "

which one the following does not reduce to sin x for every x ,where defiened,is (A)(tan x)/(sec x)(B)(sin x)/(sec^(2)x-tan^(2)x) (C) (sin^(2)x sec x)/(tan x)

If x in(-1,0), then the function f(x)=2tan^(-1)(cos ecx)+tan^(-1)(2sin x sec^(2)x) may be equal to
