Alright thanks

Implicit Differentiation question x^y = y^x I was wondering if I was right in the steps I was taking first was to take the Ln or both sides making it y Ln(x) = x Ln(y) then just taking the derivatives of both sides using product rule twice y/x + y'Ln(x) = xy'/y + ln(y)...

Thanks for the help, but I don't quite understand why you chose to multiply everything together.

physics
A proton moves in a constant electric field from point A to point B. The magnitude of the electric field is 6.4 × 10^4 N/C; and it is directed as shown in the drawing, the direction opposite to the motion of the proton. If the distance from point A to point B is 0.50 m, ...
