tan [(1) / (2) sin ^ (- 1) ((2a) / (1 + a ^ (2))) + (1) / (2) cos ^ (- 1) ((1-a ^ (2)) / (1 + a ^ (2)))] =

If A=[[1, 2, 2], [2, 1, 2], [2, 2, 1]] and A^(-1) exist and not equal to 0, then (A^(2)-4A)A^(-1)=

Find the value of 1/( 2+ 1/( 2 + 1/( 2 + 1/( 2 + ----- ∞ ) ) )

Evaluate : ( 1/2 ÷ 1/2 times 1/2 ) / ( 1/2 + 1/2 times 1/2 )

If A = [(2,2,1), (1,3,1), (1,2,2)] then A^-1+(A-5I) (AI)^2 = (i) 1/ 5 [[4,2, -1], [-1,3,1], [-1,2,4]] (ii) 1/5 [[4, -2, -1], [-1, 3, -1], [-1, -2,4]] (iii) 1/3 [[4,2, -1], [-1,3,1], [-1,2,4]] (iv) 1/3 [[4, -2, -1], [-1,3, -1], [-1, -2,4]]

Let A = {1, 2, 3} and R = {(1, 1), (2,2), (1, 2), (2, 1), (1,3)} then R is
