Differential equationsPost any interesting problems on differential equations here.

Re: Differential equationsHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20120721 22:40:59
Re: Differential equationsYou can look at both as a sum at the end of the year.

Re: Differential equationsWhoops, I have just seen something in the problem. Changed 10% to 20%. Also, you may as well take profit to be made continuously over the year.

Re: Differential equations
Now, you are talking. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #7 20120721 23:06:26
Re: Differential equationsYes.

Re: Differential equationsHave you got the answer?

Re: Differential equationsWell, there is a nice chance to do it again, if you want.

Re: Differential equationsI am playing with it right now as you know. I am getting $141105.94 to the nearest penny. What do you get? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #12 20130128 00:45:38
Re: Differential equationsI am getting $178101.29.

Re: Differential equationsHmmmm, doesn't that seem high? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #14 20130128 00:52:38
Re: Differential equationsIh, sorry. Entered 1000 instead of 10000. Your answer is correct.

Re: Differential equationsThen I am getting as the exact answer. By the way have you seen my two latest math posts? http://www.mathisfunforum.com/viewtopic.php?id=18885 http://www.mathisfunforum.com/viewtopic.php?id=18866 In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #16 20130128 02:29:29
Re: Differential equationsYes, I have.

Re: Differential equationsWhat did you think? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #18 20130128 04:19:37
Re: Differential equationsI alredy know the method for matrix decomposition you've shown in the first one.

Re: Differential equationsHmmm, so you already knew that one? How about matrix moves? You could not know that one. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #20 20130128 10:32:49
Re: Differential equationsWhich one is that?

Re: Differential equationsI knew those as well...

Re: Differential equationsImpossible, I invented that method. Gotcha! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #24 20130128 12:20:39
Re: Differential equationsNope. That is not correct.

Re: Differential equationsYep, I invented the method of getting one element. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
