Answer is (A) a=sin(A) + cos(A)........................................given as equation (1) a^2=sin^2(A) + cos^2 (A) + 2 sin(A)cos(A) a^2=1 + 2 sin(A)cos(A) therefore, sin(A)cos(A) = (a^2 - 1)/2..............................equation (2) b = {sin(A) + cos(A)} / sin(A)cos(A) b = a/a^2-1 x 2/1.............................................from equation (1) and (2) therefore b = 2a/a^2-1
