If `f(x)=cos^(-1)(2x^(2)-1), x in [-1,1].` Then

Let f(x)=cos^(-1)(2x^(2)-1) then

Let f(x)=sin^(-1)((2x)/(1+x^(2))) and g(x)=cos^(-1)((x^(2)-1)/(x^(2)+1)) . Then tha value of f(10)-g(100) is equal to

Let f(x)=sin^(-1)((2x)/(1+x^(2))) and g(x)=cos^(-1)((x^(2)-1)/(x^(2)+1)) . Then tha value of f(10)-g(100) is equal to

Let f(x)=sin^(-1)((2x)/(1+x^(2))) and g(x)=cos^(-1)((x^(2)-1)/(x^(2)+1)) . Then tha value of f(10)-g(100) is equal to

f(x)=cos^(-1)(x^(2)/sqrt(1+x^(2)))

f(x)=cos^(-1)(x^(2)/sqrt(1+x^(2)))

If f(x) = cos^(-1)[( x - x^(-1))/(x + x^(-1))] then f'( -2) is

f (x) = x cos ((1)/(x^(2))), x in 0 , f (0) = 1 at x = 0 f is

If f(x)=2x+cos^(-1) x+log (sqrt(1+x^(2))-x) , then f(x) is-
