[" Let "A=[[cos alpha,-sin alpha],[sin alpha,cos alpha]],quad (alpha in R)" such that "],[A^(32)=[[0,-1],[1,0]]" then a value of "alpha" is "]

Let A=([cos alpha,-sin alphasin alpha,cos alpha]),(alpha in R) such that A^(32)=([0,-11,0]). Then a value of alpha is:

Let A = [{:(cos alpha,- sin alpha ), ( sin alpha , cos alpha ):}], (a in R) such that A ^(32) = [{:(0,-1), (1, 0):}] is the value of alpha is (pi)/(2^(k)), then the value of k is

Let A_(alpha)=[[cos alpha,-sin alpha,osin alpha,cos alpha,00,0,1]]

Let A = [{:("cos"alpha, -"sin"alpha), ("sin"alpha, "cos"alpha"):}], (alpha in R) such that A^(32) = [{:(0, -1), (1, 0):}] . Then, a value of alpha is

If A=[[cosalpha, sin alpha] , [-sin alpha, cos alpha]] and A^(-1)=A' then alpha=

If A = [(cos alpha,sin alpha),(-sin alpha,cos alpha)] then A^(10) is equal to

cos alpha,-sin alpha,1sin alpha,cos alpha,1cos(alpha+beta),-sin(alpha+beta),1]|

cos alpha,-sin alpha,1sin alpha,cos alpha,1cos(alpha+beta),-sin(alpha+beta),1]|

If A = [(cos alpha,sin alpha),(-sin alpha,cos alpha)] , then A^(10) = .........

If A= [[cos alpha, -sin alpha],[sin alpha, cos alpha]] , then A + A'= I, the value of a is :
