Differential Equations.... 2

IIT JEE 2015 Papers › Calculus questions › Differential Equations.... 2

Simple one a) (x+y)(dx-dy)=dx+dy

Simple one b) x\left({\frac{dy}{dx}}\right)^{2}+(y-x)\frac{dy}{dx}-y = 0

Copied Questions Series

but good ones for JEE :P :D

first oneis simple...

dx-dy = [(dx+dy)\div (x+y)]

which is x-y=log(x+y) +c

second one take dy/dx=p

then solve it by puting x in LHS and differtiate wid respect to y...put dy/dx=p...and solve the differential equation..the solution is the p eliminatnt of the gven equation n the equation solved
