If a mathematical calculation is correct for mathematics, then it is also correct for physics. |
The product rule d(f)/dt = d(gh)/dt = g dh/dt + h dg/dt is correct for mathematics, it is also correct for physics. |
NO |
The d(dE)/dt = d( Fdx)/dt is correct for mathematics , it is also correct for physics. |
The d( Fdx)/dt = dF/dt dx + F d(dx/dt) is correct for mathematics , it is also correct for physics. |
The books are wrong. |
