Differential Equation

Hi 315,

This is what Wolfram Alpha says

Thank you Melody and Alan . 

Hi Alan and others,

I have only just come back to this question to take a proper look.

Prior to watching you one the forum I never treated calculus dy and dx so much like normal algebra.

To me dy/dx was glued together with super glue.

I guess I understood better when I was studying at university but I do not remember that.

It all makes such perfect sense when you show me how to do things.  

Working through this with you and WolframAlpha as a guide made it so easy.

 BUT, if I come back in a fortninght and try to do it myself I won't be able to.

Isn't that sad. :)

Students often tell me that I do not understand their learning problems, but you see I really do!    

You might prefer the following Melody:

Strictly, dy and dx should be glued together, but we science/engineering types often take liberties with the mathematics!!

Thanks Alan,

YES, that is exactly how I did do it - I was looking at yours and at Wolfram|Alpha.

But it still started by dividing everything by dx.      :/
