This applet displays tangent fields and heat maps for general solutions of explicitly defined 1st order ODEs (i.e. dy/dx = .....)
It also displays the particular solution curve; you can set the boundary condition by dragging the blue point. [Euler's method is used with or without error correction]
The applet also shows isoclines where possible [dy/dx=f(x,y) must be polynomial in x and y]
