Hi, can anyone please explain me how to understand this term? I tried to expand it, but seems I may not be right, so can anyone help me with expasion of this rhs term below? T is suppsoed to be symmetric, but when I expand it it doesn't seem to be symmetric, please help.(adsbygoogle = window.adsbygoogle || []).push({});

consider 2 mutually orthogonal directions a1,a2. associated with sides of a rectangular plane whose sides are d1,d2. and this rectangular plane is oriented at an arbitrary angle wrt global x axis.

Now consier a Transformation T as a function of (a1,a2) and (d1,d2) as :

T = [tex]\Sigma[/tex][(1/d_{i})a_{i}Xa_{i}] where i =1 to 2 andXis tensor product

when I expanded rhs of the above experssion I got:

T11 = a1 d1/d1 , T12 = a1d2/d1, T21 = a2d1/d2 , T22 = a2d2/d2

am I correct? if I am why is this not symmetric?
