If `e^(y)=(sqrt(1+x)+sqrt(1-x))/(sqrt(1+x)-sqrt(1-x))," then "(dy)/(dx)=`

If y=tan^(-1)((sqrt(1+x)-sqrt(1-x))/(sqrt(1+x)+sqrt(1-x))), find (dy)/(dx)

If y=tan^(-1){(sqrt(1+x)-sqrt(1-x))/(sqrt(1+x)+sqrt(1-x))}, find (dy)/(dx)

If y=tan^(-1)[(sqrt(1+x)-sqrt(1-x))/(sqrt(1+x)+sqrt(1-x))] then prove that (dy)/(dx)=(1)/(2sqrt(1-x^(2)))

If y=sqrt(x)+(1)/(sqrt(x)) , then (dy)/(dx)=

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

y=(tan^(-1)(sqrt(1+x^(2))+sqrt(1-x^(2))))/(sqrt(1+x^(2))-sqrt(1-x^(2))) then (dy)/(dx)

If y=sqrt((sqrt(x-1))/(sqrt(x+1)))," then "(dy)/(dx)|_(x=4)=
