Direction field/slope field

  1. Jul 27, 2005 #1
    Does anybody know how to plot the direction field of [tex]y^{\prime} = 5 - 3\sqrt{y}[/tex]?

    I get error messages because the independent variable isn't there. I've attached a mathematica notebook that shows it.

    Any help is highly appreciated.

    Your Y values cannot be less than 0 since it has a y^.5, that's what is messing you up....stick to {y, 0, 10} and you will be fine....

    You're definitely right. It has nothing to do with the independent variable, and I should have paid attention to the values of y. It works now! Thank you very much.
