Enter an equation for y' in terms of x and y to map the red point through the yellow boundaries.
How it works
Input y' = f(x, y). The slope of each arrow is the value of y' at the given (x,y) coordinate.
The red curve is a particular solution of the equation given an initial point.
Your goal: write a function so that the curve exits through both highlighted yellow
boundaries. Tap Reset for a new initial point, and boundary conditions.
