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, sin alpha)]` is (a) `-I+A` (b) `I-A` (c) `-I-A` (d) non of these

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 the identity matrix of order 2, then (I-A)[( cosalpha,-sinalpha),(sinalpha,cosalpha)] is equal to

If A = [(0,-tan""(alpha)/(2)),(tan""(alpha)/(2),0)] and I is the identity matrix of order 2 then (I-A) [(cos alpha,-sinalpha),(sinalpha,cosalpha)] is eual to

tan theta = (sin alpha-cos alpha) / (sin alpha + cos alpha)

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)[cos alpha-sin alpha sin alpha cos alpha]

If A=[[cos alpha,sin alpha],[-sin alpha,cos alpha]] then verify that A'A=I

If A=[cos alpha sin alpha-sin alpha cos alpha], then verify that A^(T)A=I_(2)

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, sin alpha)]` is (a) `-I+A` (b) `I-A` (c) `-I-A` (d) non of these
