If `y=ln((2x+1)/(x^2+1))`, then `dy/dx=?`

If y=log(x+sqrt(x^(2)-1)), then (dy)/(dx)=

If y=log((1-x^(2))/(1+x^(2)))," then "(dy)/(dx)=

If y=log((1)/(x)) then value of (dy)/(dx) at x=2 is

If y=log(x+(1)/(x)), prove that (dy)/(dx)=(x-1)/(2x(x+1))

y=log(x/(1+bx)) then (dy)/(dx)

If y=((log)_(cosx)sinx)((log)_(sinx)cosx)+sin^(-1)(2x)/(1+x^2) , then (dy)/(dx) at x=pi/2 is equal to.......

If log(xy)x^(2)+y^(2)," then: "((dy)/(dx))((dx)/(dy))=

If y = log ((1-x^(2))/(1+x^(2))) , then (dy)/(dx) is equal to

y=log ((1-sin x )/(1+sin x )),then (dy)/(dx) =

If sin(x+y)=log(x+y), then (dy)/(dx)=(a)2 (b) -2(c)1(d)-1]
