fin a triangle ABC sines of angles A and B satisfy the equation 4x^(2)-2sqrt(6)x-1=0 then cos(A-B)=

(x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

Evaluate the following: (x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

Find the number of terms in the expansion of (x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6)

In the expansion of (x+sqrt(x^(2)-1))^(6)+(x-sqrt(x^(2)-1))^(6) the number of terms is

The real value of x for which satisfies the equation ((x^(2)-6sqrt(x)+7)/(x^(2)+6sqrt(x)+7))=1 is
