halp me with physics, yes?

[paradise!]

I'm given data on Newton's Law of Cooling, the formula is:

T(s)= (To - m)*B^t+m

I'm given some data with time intervals 5 seconds apart, I have to create an equation using y=A(B^x) with newton's law of cooling.

I hope you're with me so far. So I understand everything above this, in order to find A and B I have to linearize the data by using ln. But it's not linear, I DONT UNDERSTAND!!!!!!!!!1

I don't understand why it's not linearizing, i'm doing exactly the opposite of an exponentional function by doing a natural log of it, and it's not freaking linear.

I know once I linearize that I have to take the e^(slope of linearized data) and that will be my B value.

So I need help understanding why this shit isn't linear. thanks thanks xoxoxxxo yours truly :wub:

Ask boxxy. I'm sure she's smart.

she looks so docile and contemplative in that picture

Wikipedia exists for a reason:

http://en.wikipedia.org/wiki/Heat_tr...law_of_cooling

This is also known as natural convection, as the heat transfer coefficient (h) depends on Reynold's number, the Prandtl number, the Nusselt number, and a bunch of other things.

1) I've read the wikipedia about it.

2) How the hell does that help me?

update: got it, had to subtract room temperature.

Thanks for all the great responses guys!:groovy: :groovy: they've helped me realize that if the topic doesn't include naked womanz then <10 replies.

If your name is Paradise and/or you make a thread with the word halp in it, then no one will help you.

definitely not after the last 3-4 halp threads he's made
