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 x-1/x=1/2 , then write the value of 4x^2+4/(x^2)

The minimum value of 2x^2 +x-1 is

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

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 function f(x)=x^(2)+e^(x//2) " and " g(x)=f^(-1)(x) , then the value of g'(1) is

If x_1 and x_2 are the solutions of the equation x^(log_(10)x)=100x such that x_1gt1 and x_2lt1 , the value of (x_1x_2)/2 is

If x in (0, 1) , then find the value of tan^(-1) ((1 -x^(2))/(2x)) + cos^(-1) ((1 -x^(2))/(1 + x^(2)))

If f(x)={(x^2+2,,,xge2),(1-x ,,,xlt2):} ; g(x)={(2x,,,xgt1),(3-x ,,,xle1):} then the value of lim_(x->1) f(g(x)) is
