If `x^2/x=1`,then the value of x is

If x^2+x+1=0 then the value of (x+1/x)^2+(x^2+1/(x^2))^2+...+(x^27+1/(x^27))^2 is

If x^2-x+1=0 then the value of sum_[n=1]^[5][x^n+1/x^n]^2 is:

If f(x)=2x-1, find the value of x that makes f(f(x))=9.

if sin x + sin^2 x = 1 , then the value of cos^2 x + cos^4x is

if sin x + sin^2 x = 1 , then the value of cos^2 x + cos^4x is

If sin^(-1)((5)/(x))+sin^(-1)((12)/(x))=sin^(-1)((2)/(x))+cos^(-1)((2)/(x)) then the value of x is equal to

If x >1 , then write the value of sin^(-1)((2x)/(1+x^2)) in terms of tan^(-1)x

If x-1/x=\ -1, find the value of x^2+1/(x^2)

If x-1/x=-1, find the value of x^2+1/(x^2)

If f(x)=x^2+x+1 , then find the value of 'x' for which f(x-1) =f(x)
