    Where do you teach, and why are RUclips teachers better than ones whom we pay? Great Job!

      I teach at my local high school and also at a nearby university to my hometown in the United States.....been doing it for over 34 years now. So I am definitely “someone’s classroom” teacher who is getting paid. lol And then 5 years ago, I decided “Hey, I should probably upload videos to RUclips.” It’s been fun! 👍🏻😀

    Tabular Method
    I discovered this simple method. I discovered it when I was a student at the University of Technology in Iraq, in the academic year 85/86.
    I showed it to Dr. Jalal, the mathematics teacher, who vehemently rejected it saying that it is a mechanical and non-scientific method.
    But he registered it in his own name and it was printed for the first time in the fifth edition of Thomas's book ... Engineer, Hassan Kadhim Salman

    However, I noticed that the second method (stop when you get a matching term) and the fourth method (stop when it starts to repeat, - you should get a matching term) are similar. So actually, there are three stops instead of four stops.

      @ColesWorldofMathematics  6 лет назад +1

      I tried the short-cut method putting (ln x)^3 in my derivative column and 1 in my integral column. That turned out messy. Trying the traditional Integration by Parts method letting the first u = (ln x)^3 and dv = 1 dx and then integrating by parts a second time letting u = (ln x)^2 and dv = 1 dx, I was able to arrive at a Final Answer of: x(ln x)^3 - 3x(ln x)^2 - 6xln x - 6x + C

    But there is a need of a mnemonical trick on formula of integration by parts. As it is confusive that the first function will be write as it is or in derivative or in integral form.
    So please , upload a trick which should be an alphabatic representation of the mechanism of integration by part formula in the pattern *(first function is as it is then integral of second function then minus sign then whole integral of derivative of first fuction and then imtegral of second function).

    • @carultch

      I learned the mnemonic of "Ultraviolet Voodoo". Since u*v - integral v*du, looks like uv for ultraviolet, and v du looks like voodoo.
      Why anyone even bothers to teach the traditional formula for integration by parts, I don't understand. The tabular method is so much easier to use, and so much less subject to error.

    I noticed that when you have to do that backwards integration, it's a waste of time to do the algebra. You can just multiply the coefficients, then multiply them by -1, then add 1 and bingo.... You have the number that divides your terms. It's less intuitive, but is quicker.

      Construct IBP table:
      S_____D_____I
      +_____x____cos(2*x)
      - _____1____1/2*sin(2*x)
      +_____0____-1/4*cos(2*x)
      IBP result for indefinite integral:
      1/2*x*sin(2*x) + 1/4*cos(2*x) + C
      Evaluate from 0 to pi/2:
      (1/2*pi/2*sin(2*pi/2) + 1/4*cos(2*pi/2) ) - (1/2*0*sin(2*0) + 1/4*cos(2*0))

    Can this method apply to integrals which consist of more than 2 functions. Ex e^x(1+secx)tanx
    Assume a function f(x) can it be integrated by dividing it into 1 as differentiation part and f(x) as integration part

    I dont understand why in the matching terms cases you integrated “backwards” at the end if you are ultimately multiplying the two Columns it would be better multiplying “forwards ” being less confusing.
    Looking forward for your reply and thanks for the video

    • @ColesWorldofMathematics
      @ColesWorldofMathematics  5 лет назад

      Sorry it took so long to reply! Sometimes I get behind in my replies.
      Multiplying forward would probably be easier. But the first time I learned this trick, the integration was done backwards. If I had to guess, it's because after you do the previous multiplication on the angle, you are technically at the bottom of the right-hand column, so to continue a smooth transition, it makes sense to multiply backwards across that last row.

    For all of those who are thinking that this rule applies to all of the problems related to integration by parts,for your kind information,you are wrong 😁😀.It applies only to functions having the form integration x^n f (x)...Cheers!!!!

      The short-cut is not intended to be for every integration by parts problem. Sometimes, it makes IBP easier, and when it does, that would be a good time to use this method.

    do a video on inverse circular function formulas please.

    thanks for the short cut ! can u pls tell that a following order kind of thing .. like (LIATE) probably .. that refers the order logarithmic, inverse trig, algebraic,trig,exponential .. functions. so for the U*V ( for the functions to be prefered at the first while multiplying it with other) so can u just tell me , is there any thing that we also need to follow these, while doing it in this type of method(bcoz here exponential is first and the (e^2x.cosx) trig is the next) ---
    -THANK YOU

      At the beginning of this video ( ruclips.net/video/C1pJsJE7QO0/видео.html ), I talk about the mnemonic LIPTE which is often used to help pick the "u" and the "dv". Hope it helps. Thanks for watching.

    Hi,
    The video was amazing, but I m facing a problem with integrating sec^3 x using DI method.
    what i did is, i first split it into sec x . sec^2 x then tried DI method but the integrals and differenciations keeps on becoming bigger and bigger.
    Please advice what to do. :)

      You can integrate sec^3 x using a reduction formula. The steps are outlined for you via an online integral calculator. See this link: www.dropbox.com/s/mhd2wb3thl9bk6z/Integral%20Sec%5E3%20x.pdf?dl=0
