If `y=2^(-2^((1/(1-x)))` , then find `lim_(x->1^+)y`

If y=2^(-2)((1)/(1-x)), then find lim_(x rarr1^(+))y

If y=(x+1)(x^(2)+1)(x^(4)+1)(x^(8)+1) , then lim_(x rarr -1) (dy)/(dx)=

If x=1 then find x+y=-2 , y=?

If x=1 then find x+y=-2,y=?

If y=(sin^(-1)x cos^(-1)((x^2)/2))/(1+x^2) then find the value of y(1/2) + y(1/sqrt2) + y(-1/2) + y(-1/sqrt2)

y=log_e((1+x^2)/(1-x^2)) then find 225(y''-y') at x=1/2

If ((x_(1),x_(2)),((y_(1),y_(2))-((2,3),(0,1)),=((3,5),(1,2)) then find x_(1),x_(2),y_(1),y_(2) ,

If x = 1 , and x + y = -2 , then find y

If f(x+ y) = f(x) + f(y) for x, y in R and f(1) = 1, then find the value of lim_(x->0)(2^(f(tan x)-2^f(sin x)))/(x^2*f(sin x))
