Solved!

Plotting implicit differentiation equation

HP Recommended
HP Prime

Hi All,

 

I would like to plot the graph of the following equation on the HP Prime:

 

dy/dx = (9/2y)*(2x - x^3)

 

I have attempted to use the Advanced Graphing App but I am not able to enter the equation correctly so that I can graph it.

 

Thanks,

Athanasios

In my opinion this is an explicit differential equation, or ordinary differential equation.


The solutions are easily found, and implicit relations:
y^2=9(x^2-x^4/4)+c


We can plot them in the Advanced Graphing app.
