Please help!!
The area of a rectangle with dimensions x and y is A(xy)=xy. Find the differential of this function.
dA=
If you measure x=6 and y=10, with a measurement error of +/ 0.16, use the differential to estimate the possible error in the caculated area. (Assume that all expressions are in cm. Do not include units in your answer.)

Best ResponseYou've already chosen the best response.1Think of the differential equation as saying the change in A = y times the change in x + x times the change in y.\[\Delta A = y * \Delta x + x * \Delta y.\] Plug your x and y values into their appropriate x and y variables. The change in x could be as much as + or  .16. So plug .16 in delta y and delta x. \[\Delta A = 10(\Delta 0.16) + 6(\Delta 0.16)\] There are questions (on psets/exams) later on in the course that use this concept.
