If A = `[(0,-tan""(theta)/(2)),(tan""(theta)/(2),0)]` and I is the `2xx2` unit matrix, find `(I+A)(I-A)^(-1)`.

If A = [(1,tan""(theta)/(2)),(-tan""(theta)/(2),1)] and AB = I_(2) , then B=

If A=[(1,tan(theta/2)),(-tan(theta/2),1)] and AB=I , then B=

If A=[[1, tan((theta)/(2))], [-tan((theta)/(2)), 1]] and AB=I , then B=

If A=[{:(4,2),(-1,1):}] and I is the 2xx2 unit matrix, find (A-2I)(A-3I)

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=[(0,-tan (alpha/2)),(tan (alpha/2),0)] and I is 2 xx 2 unit matrix, then (I-A)[(cos alpha,-sin alpha),(sin alpha, cos alpha)] is

If A=[(0,-tan (alpha/2)),(tan (alpha/2),0)] and I is 2 xx 2 unit matrix, then (I-A)[(cos alpha,-sin alpha),(sin alpha, cos alpha)] is

If A=[(0,-tan (alpha/2)),(tan (alpha/2),0)] and I is 2 xx 2 unit matrix, then (I-A)[(cos alpha,-sin alpha),(sin alpha, cos alpha)] is
