Thanks again, but that looks like gibberish to me. I've never used sigma outside of physics, for example. Maybe it wouldn't be that hard to learn, but I did google least squares and none of it really made sense to me.

@ zach: Thanks, but no idea how to do that. And I posted this in the wrong subforum, because I'm in advanced pre-calc. So no calculus to help me please. @lane: it's not experimental. That's an interesting idea though. I'll try it. Thanks a lot.

Homework Statement Derive an equation of the form y=ax^b to model the given data: (35, 0.01) (28, 0.03) (20, 0.1) (15, 0.3) (11, 1) (9,3) (6, 10) (4.5, 30) Homework Equations Well, I know the answer is y = (7790 +/- 1246)x^(-3.698+/-0.1036) because that's what LoggerPro spits out, but...

Okay thanks a lot guys. I think this will definitely get me started.

Thanks, but since we haven't gone into any more detail with light than diffraction and refraction and stuff like that, I can't really use that too much. Thanks for the input though. Anyone else?

Anyone know how this would work?

Well, since the net force = 0, and they are opposing, we know that Fg1 = Fg2. Thus, GMfirststarMspaceship/0.8^2 = GMsecondstarMspaceship/0.2^2. G and the mass of the spaceship can be divided out of the equation, leaving us with Mstar1/0.8^2 = Mstar2/0.2^2. Thus, Mstar1/Mstar2 = 0.8^2/0.2^2. So...

I'm conducting a lab in which I change the distance of a lamp from a solar panel and use a multimeter to measure the resulting voltage. What type of relationship am I supposed to find? My results seem to indicate either a relationship with either a quadratic equation as its model or an inverse...
