   My question is, derive an equation to find the maximum range of a projectile thats not on level ground. I am lost and i did attempt this, by making a diagram and subbing in what i thought i would need to use, but i still have not come up with the answer. plz help

   I think the best thing you can do is post whatever you have done. I could suggest a lot but I don't know what is making you go wrong.

   Substitute
   [tex]y=R\ sin\alpha[/tex]
   and
   [tex]x=R\ cos\alpha[/tex]
   in the parabolic equation for the projectile.
   The range will then be a function of [itex]\theta[/itex].The turning point of a function occurs where the derivative is zero...
