    There is a problem with the site, the solutions aren’t showing please fix it and thank you (It was working just a few hours ago)

    Hello. Good morning everyone. I had a question that is rolling into my mind. Maybe someone can give it a reasonable response. Is it possible with a tolerable error to approximate any graphed function with Taylor polynomials, using tricks, and if necessary o notation? Thank you very much

  5. Alberto Balsalm says:

    Firstly, a big thank you to RoRi for putting together these solutions! I’ve been working through the book with them side by side for about 8 months now (currently on chapter 8)

    If anyone here is seeking the solutions for chapters 15 + 16, I have found the following pdf:

    https://www.docdroid.net/Zk7cRFF/apostol-final-chapters-pdf

    no luck yet on chapter 14, and I would still very much like to find the solutions for vol 2! If you find any of these, please link it in the comments

  6. Astyute Chick says:

    Does anyone have any updates on Rori’s current plans? I really loved his solutions to Vol. 1 of Calculus from Tom Apostol. Is he planning to finish the final few questions in this volume and move on to Vol. 2? If so, when?

    • Evangelos says:

      I’ve been working on this book on and off for much longer than I care to admit, and filling in missing solutions in the comments of this blog when possible. If/when I make it to Volume 2, I think I’m going to start a WordPress blog similar to this one to catalogue my solutions. I’ll post a link somewhere on this site when the time comes

  7. Matthew Brenneman says:

    Hi, I’m interested in doing self-study and the solutions would be a godsend for me. However I’m not finding a link to the solutions. Could you kindly tell me where that is? Thank you?

    Why is there no solutions for the 14th chapter???
    Please be kind it enough to notify me..I have my finals coming

    • Matthew Brenneman says:

      Do you know where the link to the solutions are? For some reason I can’t find them. Thank you

    Thanks for providing your solutions! I just embarked on the journey of college maths and this is a first year-long course that I took. it helps to cross-check my answers with yours.

  11. tom says:

    Rori – this blog and solutions has been very helpful in my math journey. The presentation is so clear and concise I think you could continue these endeavors for more books and ask for donations- but alas you probably have higher aspirations than this. I am almost done with Calc. 1 after more than 3 years- without answers I can’t imagine how much extra time it would take. I assumed that Apostol, Spivak and Courant covered the same material, and although they play well off each other, the combined span of the 3 is much greater than any one. Hopefully can read most of the books in your list, although a rough estimate of the time frame would be 20 years. Oh well, it’s the journey that counts. Thanks again!

  12. Jon Poler says:

    Hi Rori. This is amazing! Thank you so much for your effort!

    Suppose that someone wanted to work through Apostol, but doesn’t have time to complete every exercise exhaustively. Would you be able to comment on good heuristics for choosing a subset of the problems to solve while still getting 80-90% of the understanding? I’d like to work through vol 1 and 2.

    • Mal says:

      Recommend Open Courseware at MIT – Calculus with Theory and Multivariable Calculus with Theory. They have readings / recitations/ assignments and exams based on these texts.

  13. Manvi says:

    Thanks for the solutions, it was really helpful. I hope you can also help me with chapter 16 solutions. Thanks!

  14. Otay says:

    On the partial fractions exercises in 6.25 that involve trigonometry, how do you know when to use the u=tan(x/2) substitution? Or more importantly, when not to? (I would have never thought of the manipulation you used on #31. I tried u=tan(x/2) and failed.)

    P.S. Thank you so very much for all of this. Bless you.

  15. Gabriel Rangel says:

    Apostol’s book never ceases to make me feel stupid, which is why I chose it. But I don’t think I could get through without your solutions, thank you.
    I hope you get to vol 2 by the next semester.
    Keep up the good work!

  16. Stupendous says:

    I see that there are no more solutions from chapter 8 – Introduction to Differential Equations onwards. Also, are you going to make solutions for volume 2 as well? Thanks for creating the wonderful solution guide by the way!

    • RoRi says:

      Hi. I’m just finishing Chapter 7 tonight (still 2 more problems). I’ll start on Chapter 8 tomorrow. The plan is to average 5 problems per day over the course of each month (if you look at the archives on the side you’ll see that each month has 150 or 155 entries), which means I’ll finish volume 1 on June 23. I will definitely do volume 2, but maybe not right away. I was thinking of blogging the solutions to either a linear algebra book or a topology book after I finish volume 1. (It makes more sense for my coursework to do one of those rather than a multivariable calculus book.)

      No problem on creating the solutions. Please let me know if you find any mistakes or typos or anything.

      • tom says:

        June 23 is the beginning of summer- well timed! I also am looking forward to being finished by about beginning of summer, with the trifecta of calculus books (spivak, courant and apostol; admittingly dependent on your work). I can’t tell you how valuable this stuff is to a self learner. I have been thru spivak twice now due to the sheer volume of questions, in spite of having solutions; the first time thru I was little more then a proof confirming robot while the second time I am able to grasp the landscape, so to speak. My next books will probably be analysis by Pugh, and Taos. Any interest in working those books?

      • RoRi says:

        I might do an analysis book at some point, but it will be a while. Currently, the next three books I plan to do are Hoffman & Kunze’s Linear Algebra, Willard’s General Topology, and Volume 2 of Apostol. (Not necessarily in that order.) If I can maintain a 5 problem per day pace, doing all of the exercises in those three will take me until December 8, 2017 (modulo possible counting errors). So… even if I do an analysis book it’s going to be a long time before I get started. There are a number of solution sets (of varying quality) to Rudin’s Principles of Mathematical Analysis floating around online. I think there are also solutions out there for Apostol’s Mathematical Analysis.

        Also, I think you asked a question about this exercise back in November? I did finally get around to updating that. I don’t have anything insightful to say about the motivation for the problem, but at least the solution should now be mathematically correct (I hope).

      • tom says:

        I will be looking forward to seeing your next work. I am geared to attack analysis soon which I give myself until Dec. 2017- conveniently the time you stated for the 3 books. Certainly the Apostol II and the Linear Algebra look very enticing. Perhaps one day the topo….

  17. RC Fernandez says:

    This is gold. The only material i could find on the internet.

    I would love to print on a paper, do you have any compiled version ? Such as pdf, txt or whatever. It will give me a hell of a job to put it all together in one file just to print. Pls say that you have.

    • RoRi says:

      I’m really sorry, but I do not have a PDF of the blog. All of the pages are generated by WordPress and the images with math are inserted using a plug-in. I should probably make a FAQ that explains this at some point since people are asking for PDFs. I also want to keep it in blog format so that people can leave comments and follow the links to previous results when they are necessary.

Point out an error, ask a question, offer an alternative solution (to use Latex type [latexpage] at the top of your comment):
