2) 3) 4) 5) 6) 7) 8) a-x b If a+b+c= 0 and c a = 0 then prove that either x = 0 or x = (a + b +c) b a C-X HA=[PO] is such that A = I then find the value of 1-P+qr If cose sine If A = and A+ AT = 1. Find the possible values of 0 0=1 sin cose 0 0=11/3 Inverse of a square matrix is unique. Give an example to prove it? x-3 x-4 x-a Prove that x-2 x-3 x-b=0 x-1 x-2 xX-C where a, b, c are in A.P. a Using properties of Determinants prove that : - 31 Express as sum of the symmetric 4 (b + c) ab ab Prove that ca a b-x (a + c) bc ac+c ac c skew symmetric matrices. ca bc = 2abc(a+b+c) dict.com (a+b) = 4abc (Use properties to prove the above)
