24why has this been given ???
S={(a,b)εR*R:x=a,y=b,(2xy-3x^2y)=constant→dy/dx>0}
S'={(x,y)εA*B:-1≤A≤B AND -1≤B≤1}
some expert plz reply
if x is increasing at the rate of 2cm/s at the instant when x=3cm and y=1cm ,at what rate y must be changing in order that the quantity (2xy-3x^2y)shall neither be increasing nor decreasing ....
