,.,.,.hello to all forum users, I would like to know how to show or come to the solution of this oscillatory integral wolfram alpha program does not give the correct solution, I hope will be a real challenge for you,,. greetings from Colombia.,.,.,,..,,,...Integrate[ Sin[E^x^(4)], {x, 2...

hi all, as I had said before I will continue publishing mistakes math programs, I recommend you look well put pictures that the integrals are simple but the program fails with the change of variable and can not develop and other computer does not understand the substitutions that are also...

hello...interesting, but as I said in my previous forum topic or main focus is that you develop by various methods ... one can be evaluated by the summation properties and then calculate its limit for example,,,,,,,, if you are can't make exercise , there is not problem,,,, thanks... att...

hello ... I propose this exercise for you to solve on various methods ...\[\lim_{n \to{+}\infty}{\frac{1}{n}\sum_{i=1}^n({1+\frac{i}{n}}})^{-2}\]thanks att jefferson alexander vitola(Smile)

Re: L-R Circuit Simple hello ... MarkFL wanted to ask in this exercise that I not included the other sheet where I resolved scanned electric charge point at time t, if I scan this one could include in the photos that I gave to principle for the exercise remains continuous all the consecutive...

Re: L-R Circuit Simple hello ... I accept your criticism and comments, but do circuit drawings or drawings on the approximation of the rectangles double integrals, if They Can not make latex, I have seen a post by the other user approximation on double integrals, and although the user will use...

hello ... I'll put some solution, as I do not drive the latex language, then I take pictures of the leaves with my solutions ... the user who wants to give more solutions is well received and is welcome ... https://www.physicsforums.com/attachments/1069

hello ... I wanted to demonstrate the solution of a differential equation, and as I do not yet know the latex language, then I take pictures of the leaves with my solutions ... the user who wants to give more solutions is well received and is welcome ... att jefferson alexander vitola (Smile)...

hello,,,,,,,,,,,,,,,,, I want to compare my method and style,,,, if I Realize That the numerical method of you is better than mine, I simply do I give up and will not work more,,, so I wanted to know how you solved it, ,,, the question for me is not a homework task is not,,,,, so far it...

hello,,,,,,, fantastic,,,,, what your method is interesting,,,,,,,, my intention is not to force you or force you to show your procedures, you are all free not to do it,,,, what I have said is that I find it strange that you ask me first see my results and methods developed by me, and if after...

jajajajajjaja:o the joke is good,,,,,, just when you want to try to solve it, I'll wait,,,,,, My main purpose is to know you how you would address the problem and apply methods to solve oscillatory integral,,,,,,, att jefferson alexander vitola(Bigsmile)

hello,,,,,,,,,,,,,,,, you did not answer me about that in the code you wrote was not 70 it was 73,,,,,,, and how this would have involved influence and the approximate solution of the integral oscillatory,,,,,, I think until I see real contributions made by you, with your procedures and steps...

hello,,,,,,,,,,,,,,,,,,, ,,,,,,,this is correct,,,,,,,,,,,,,,,,,now the important is how you what your procedures and methods you use to reach this approximation, this is true essence and the importance of my proposed,,,,,att jefferson alexander vitola(Bigsmile)

hello,,,,,,,,,,,,,,,,,,,,,, I do not know the program that you use to approximate the integral,,,,,,,which program is using?,,,,,you wrote in your code 70 and it was 73,,,,, I think it does not affect much the approximate solution but then only with my method,,,,, with your method suddenly yours...

hello,,,,,,,,,,,,,,, with Respect to That first I must show my Routines and solutions, I think I am the only user who asks a question about an exercise and they said Can not resolve,and they said what first i be must show me solved what make, What you'll wait to solve the exercise and not...
