Thanks a lot. That's cool!

How can I use the W function to solve for t? a = bt + e^(ct), where a,b,c,e are known constants. e is Euler's number. t is the unknown? I have only seen examples where a = 0. Thanks.

Thanks a lot StatusX. That's pretty much it. I hope now Rodou understands that I never said that the entire area has to filled with circles. I only wanted to know the max amount of circles that can be incorporated into a bigger circle. Since form the website there is no clear way to go about it...

What you're saying I already mentioned explicitely. Who said that every point in the circle needs to be occupied by a circle? I only said that the circles need to be touching without overlapping. The question never even mentioned that every point needs to be occupied. And by the way, I never...

Could you imagine 2 circles inside a much bigger circle?

thanks, but who said anything about n -> infinity? When I said n I meant a number. Remember also that R could be >> r. Do not assume anything I haven't told you except maybe that all adjacent circles are touching themselves without overlaping. Thanks for the interest though.

How did you get that?

Hi, this is the question: If the area of a circle C is A and there are n circles of radius r that do not overlap, inscribed on C, what is r? I was thinking of A = n(pi)r^2, or the area of C equals the sum of the areas of the circles with radius r to get r, but since there is space in...

if I say that there are 50 circles, n = 50, inscribed in circle C which has area A, and all adjacent circles are touching each other whithout overlaping, then what is their radius? That's what the question means. (I think)

Hi. I'm having trouble solving for t: 1180 = 98t + 1080e^(-t/10) I know basic properties but I think I am not remembering some idea or specific property to be able to solve this. Thank you for any help.

Thank you so much for every single comment. I found all of them very helpful. I am glad I decided to start the thread. Wow, only a few hours ago I wrote this, and there are ten replys already. You people are great! Like some of the replys state, I think for a situation like this, maybe the best...

Hello everyone! I'm in 12th grade and having trouble finally deciding what to choose between Electrical Engineering and Theoretical Physics. My real problem is that I love Math and Physics and false modesty apart, I think I'm good at it.( I haven't entered into University yet but presently I...

Hello everyone! My problem is easy to explain but somewhat hard. I have to make an ultimate final decision between Physics Engineering and Electrical Engineering:confused: . I tend to be more physics inclined, but I am not sure. I know that ultimately is a conclusion that I by myself must be...

But hey, I meant hard but not that hard. Can you lower the bar a little bit more? Also, any good books with the types of problems discribed that are mentioned would be appreciated. Thanks.
