If `A=1/9[-8 1 4 4 4 7 1-8 4]` , prove that `A^(-1)=A^T` .

If A=1/9[[-8,1,4],[4,4,7],[1,-8,4]], show that A^-1=A'.

If A = 1/9 [(-8,1,4),(4,4,7),(1,-8,4)] , show that A^-1 = A'

If A=[[ 1 ,4 , 7 ] , [2 , 5 , 8 ]] and B=[[-3, 4 , 0 ],[ 4 ,-2 , -1 ]] then show that ( A + B )^T = A^T + B^T

If t = 1 - 1/8 + (1.3)/(8.16) -(1.3.5)/(8.16.24) + …… then prove that 5t^2 = 4

If t = 1 - 1/8 + (1.3)/(8.16) -(1.3.5)/(8.16.24) + …… then prove that 5t^2 = 4

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then prove S-T=S nn T'

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then prove (S nn T)' = S' uu T'

Prove that: cos4A=1-8cos^(2)A+8cos^(4)A

If R = {2, 4, 6, 8} S = {3, 4, 6, 7} T = {1, 2, 3, 4} are three subsets of the Universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} then prove (R uu S)' = R' nn S'
