Match the statement/expressions in Column I with the statements/expressions in Column II. Column I Column II The minimum value of `(x^2+2x+4)/(x+2)` is (p) 0 Let `Aa n dBb e3x3` matrices of real numbers, where A is symmetric, B is skew symmetric, and `(A+B)(A-B)=(A-B)(A+B)` if `(A B)^t=(-1)^kA B ,` where `(A B)^t` is the transpose of the matrix `A B` , then the possible values of `k` are (q) 1 Let `a=(log)_3(log)_3 2.` An integer `k` satisfying `1<2^(-k+3^((-1)))<2,` must be less than (r) 2 In `sintheta=cosvarphi,` then the possible values of `1/pi(theta+-varphi-pi/2)` are (s) 3
