If `A = [(0,-tan(alpha//2)),(tan(alpha//2),0)]` and `I` is a `2xx2` unit matrix, prove that `I+A=(I-A)[(cosalpha,-sinalpha),(sinalpha,cosalpha)]`

If A_(alpha)=[(cosalpha,-sinalpha),(sinalpha,cosalpha)] , then

If A={:[(0,-tan.alpha/2),(tan.alpha/2,0)]:} and I is the identify matrix of order 2, Show that I+A=(I-A) {:[(cosalpha,-sinalpha),(sinalpha,cosalpha)]:} .

If A=[{:(0,"tan"(alpha)/(2)),("tan"(alpha)/(2),0):}] and I theidentity matrix of order 2, show that I+A=(I-A)[{:(cosalpha,-sinalpha),(sinalpha,cosalpha):}] .

Let A=[(0,-tan(alpha/2)),(tan(alpha/2),0)] and I be the identity matrix of order 2. Show that I+A=(I-A)[cosalpha-sin alpha sin alpha cosalpha] .

Let A=[0-tan(alpha//2)tan(alpha//2)0] and I be the identity matrix of order 2. Show that I+A=(I-A)[cosalpha-sinalphasinalphacosalpha] .

If A=[[0,-tan alpha2,tan alpha2,tan alpha]] and I is 2xx2 unit matrix,then (I-A)[[cos alpha,sin alphasin alpha,sin alphasin alpha,sin alpha]] is (a) these

If A=[(cos alpha,sinalpha),(-sinalpha,cosalpha)] , verify that A'A=I_2

If A=[{:(cosalpha,sinalpha),(-sinalpha,cosalpha):}] , show that A'A=I.
