Simple and best practice solution for 1 2ydx 4 xdy0 equation check how easy it is and learn it for the future our solution is simple and easy to understand so dont hesitate to use it as a solution of your homework. For example if we have yx2 then we could find the gradient at a given point by doing x dx2 x2 dx where dx is very small this is simply by thinking about the y coordinates if we move dx along the x axis exanding the brackets simplifying and then removing any terms with dx as they will tend to 0 gives the expected result 2x.
