Hi,
I have 2x+3y=0 equation, I need to find x and y points to draw a line on plane. Can anyone help me?

There are infinitely-many pairs (x,y) satisfying the equation. Choose a value for either x, y and solve for the other to get a pair .
 
Thread 'Derivation of equations of stress tensor transformation'
Hello ! I derived equations of stress tensor 2D transformation. Some details: I have plane ABCD in two cases (see top on the pic) and I know tensor components for case 1 only. Only plane ABCD rotate in two cases (top of the picture) but not coordinate system. Coordinate system rotates only on the bottom of picture. I want to obtain expression that connects tensor for case 1 and tensor for case 2. My attempt: Are these equations correct? Is there more easier expression for stress tensor...
