xy/(x-y)
New concept and I'm having trouble with ones that are not linear equations. Could someone help me out?
linear, non-linear, makes little difference. you want to find and for
to find the first, differentiate with respect to x twice. that is, treat y as a constant. so you would just differentiate normally thinking of y as just any other number, like 2 or something.
a similar approach can get you
can you start?
