If A=[cos x-sin x sin x cos x], find AA^(T)

If A=[[cosx,-sinx],[sinx,cosx]] , find A A^T

If A=[(cosx,-sinx),(sinx,cosx)] , then A A^(T) is

If A=[[cosx,sinx],[-sinx,cosx]] , when A + A^T= I find x satisfying 0 < x < pi/2

If A=[{:(cosx,sinx),(-sinx,cosx)] then find |A|

If A=[{:(cosx,sinx),(-sinx,cosx)] then find |A|

If A=[{:(cosx,sinx),(-sinx,cosx)] then find |A|

If A^T=[[cosx,sinx],[-sinx,cosx]] ,Verify that A^TA=I

If f(x)=|(cosx,cosx,sinx),(-cosx,cosx,-sinx),(sinx,sinx,cosx)| , then find its determinant
