if I am given a dy/dx equation how do I match it up to the slopefield

anonymous · Answer

Plug in points $(x,y)$ of your choice.

For example, if $\dfrac{dy}{dx}=xy$, you can plug in $(0,0)$ and you have $\dfrac{dy}{dx}=0$. If you pick $(1,1)$, $\dfrac{dy}{dx}=1$. And so on.

Look for lines of equal slope on the slopefield. "Where is dy/dx = 0 ? Where is dy/dx > 0?, Where is dy/dx < 0? Where is dy/dx not defined? etc.

Thanks not sure this is what I was looking for.  But I am working some problems out using slopefields.

What are the problems asking you to do?

precal · Answer

They are misc. AP problems.  Just stuck on them.

They are just really awful problems.  I finally figured out how to use my TI-89
