(a+2)(a-1)

the value of sqrt(1(1)/(2)-[1(1)/(2)-1(1)/(2)+(1(1)/(2)-1(1)/(2)-1(1)/(4))]) is

The expression (2^(2)+1)/(2^(2)-1)+(3^(2)+1)/(3^(2)-1)+(4^(2)+1)/(4^(2)-1)+((2011)^(2)+1)/((2011)^(2)-1) lies in the interval

A=[(1,2),(2,1)], then adjoint of A is equal to (A) [(1,-2),(-2,1)] (B) [(2,1),(2,1)] (C) [(1,-2),(-2,1)] (D) [(-1,2),(2,-1)]

Find the value of (1-1/(2^(2)))(1-1/(3^(2)))(1-1/(4^(2)))(1-1/(5^(2)))…….(1-1/(9^(2)))(1-1/(10^(2)))

The value of ((1)/(2)-:(1)/(2)"of "(1)/(2))/((1)/(2)+(1)/(2) "of"(1)/(2)) is

1+(1)/(2)+(1)/(2^(2))+...+(1)/(2^(n-1))=
