I´m new at js and I´m trying to draw a circle, but there is still something wrong.

Math.pow(r,2) = Math.pow(y,2)+Math.pow(x,2);

I´m new at js and I´m trying to draw a circle, but there is still something wrong.
Maybe someone could help...

function msg_float(x)
{
   Math.pow(r,2) = Math.pow(y,2)+Math.pow(x,2);
    outlet(0, y);
}

not actually sure what you are trying to do (my math skills are bad!!) but it looks like r2 = x2 + y2. you are trying to assign the result of your equation (y2+x2) to a function Math.pow(r,2), which doesn't make sense since Math.pow is returning a value. You can only pass it a value inside the (). also y is never defined and you are trying to send it to your outlet.

The below should work and give you r2 (y is a constant right now).

I'm sure someone with more js and math chops will explain it better, but maybe this will get you started.

you got me on the right path, I tried to assign a function to a value, I have to solve the equation for y, then it works, code blow.

y = Math.sqrt(Math.pow(r,2) - Math.pow(x,2));
