xy=sec(x+y)

Find (dy)/(dx) when x and y are connected by the relation given: sec(x+ y) = xy

lim_ (x rarr0) ((x + y) sec (x + y) -y sec y) / (x)

If (sec x)^y = (sec y)^x then find dy/dx .

The general solution of the differential equation x.cos(y/x)(ydx+xdy)=y sin(y/x)(xdy-ydx) is (A) xy=c sec((x)/(y)) (B) y=xc sec((x)/(y)) (C) xy=c sec((y)/(x)) (D) None of these

sec(x+y) = xy

If sec (x+y) = xy, then find (dy)/(dx)

If sec(x+y) = xy find dy//dx

Find dy/dx if sec(x+y) = xy

Find dy/dx if sec(x+y) = xy
