I seem to be lost at deriving an equation for the medium area, A.
I understand the tansfer from low temp area to high. Pcond...
Statics: If computing the moment of inertia about the y-axis of a triangular shape in the 2nd quadrant(not touching the x-axis); would i still use hb^3 /12
People I am fairly new with dealing with DEs (and here I was thinking I got it all :palm: )
Any who: I am working on some problems here and the professor wants us to use 2 methods to solve this DE. My issue is I can't figure out what the 2nd method is!
(dY)/dt=AY +F
^{Y} = [7,4,4; -6,-4,-7...
