Power Series - Made Easy! | Power Series Representation of a Function | Math with Professor V

How to find the power series representation of various functions MADE EASY! I break down the process into 3 main cases, and work through lots of examples so that you can become a professional at mastering this concept as well.

At 12:37 isn't it 2^(4n +4) instead of +2?

[@mathwithprofessorv]

Yes! Thanks for catching that! Whoops 😬

[@ashleycook1174]

I have not been able to find a video on this concept that was so well-explained, thorough, and REASSURING. It's one thing to understand the material and make a video about it, but it's another thing to be able to teach it as thoughtfully as you did. Thank you SO much.

[@mathwithprofessorv]

You are so very welcome! Thank you for your comment-I truly appreciate it! ☺️❤️❤️❤️ I put my heart into teaching math and it brings me such joy and fulfillment when I hear feedback like yours. Wishing you lots of success!!!

[@ProfessorJDawg]

Your unwavering dedication and the extraordinary clarity in your explanations have left me in awe. You truly embody the essence of an exceptional teacher, and it is evident that we could greatly benefit from the influence of more individuals with your remarkable pedagogical skills.

[@mathwithprofessorv]

Thank you so much for your incredibly kind words-it means a lot to me since I’m passionate about what I do and want to make learning calculus as easy and accessible as possible for my students and students around the world. ☺️

[@mistermeatballs7800]

I haven't found a more concise explanation for power series representation online than this - this is really well done, liked and subscribed

[@mathwithprofessorv]

Thank you so much for your support and kind words!!!! 🙏🏻☺️

[@koala1578]

You're so right mistermeatballs7800

[@minhluanne7462]

agree with u

[@santaclaus2480]

Isn’t there an error in q3 distributing ( 2^4)^(n+1)? Should it not be (2)^(4n+4)?

[@davytong3157]

I was having an anxiety attack because I couldnt figure out how to do this, not only did you explain everything perfectly and answered all my questions, you assured me and made me feel okay, thank you

[@mathwithprofessorv]

Of course-it is an honor! Comments like yours make me know this is all worth it and I’m doing what I’m supposed to do. You are more than capable of mastering this topic, and a professor who understands it thoroughly can explain it in an understandable way that isn’t intimidating. Wishing you lots of success!!! ☺️☺️☺️🫶🏻🫶🏻🎉

[@arosdeluna]

this is the best video of Power Series Representation of function in youtube, thank u so much, this was very helpful for studying

you explain so cool! the way you made it into 3 groups was great so now ik what to do while going through
problems

[@mathwithprofessorv]

Oh I’m so so glad!!!! It makes the topic so much more manageable, right? ☺️

[@melikare1530]

absolutely! i have a question. what should we do when they want us to do this in reverse? like when we are given what we got as an answer here and wanting to turn it back to the function? (sigma to function as in finding the sum instead of going through function to sigma)@@mathwithprofessorv

[@zianiera]

An excellent teacher

[@mathwithprofessorv]

Thank you! ☺️☺️

[@azrayns]

Hello. Can a sum series in the form an.x^n have a convergence interval (-3/2,+3/2]? There was such a question in our exam, do you have any idea how to solve such questions?

[@ruhailmir]

Superb!!, you made everything so fun, plus you have amazing handwriting, thanks for the video. 😊

[@mathwithprofessorv]

Thank you so much 😀 You’re very welcome!

[@nickchandra4890]

Thank you. I am struggling to apply this to e^x/(1+3x)^2

[@user-jx5bg1cl6q]

Thanks alot ❤

[@mathwithprofessorv]

You’re so welcome!

[@pobo-]

thanks for teaching me 🌷

[@pobo-]

it's actually 2^(4n+4) around 13:15 but it's a small calculating mistake

[@mathwithprofessorv]

My pleasure 😊

[@ishaanbaruah8968]

At 25:22 is it (-1)^(n+2)? since we subtract one from the index and add 1 to all the n terms in the series?

[@davidlightfoot3217]

Genuinely think this video saved my test grade. Thank you. This was so much clearer than anything I've seen thus far. Breaking down how you got to every step and thoroughly explaining everything is extremely helpful. Every other video I've seen and even my professor just fly through everything. So once again, thank you!

[@mathwithprofessorv]

You are most welcome! Happy to help. Please share and subscribe, it would mean so much to me. ☺️🙏🏻

[@DraftingCADemy2023]

what would be its interval @20:49

[@Yuna-wt4ny]

❤❤❤

[@satellite1975128]

At 30:16, the denominator inside the sum should be 5^n, not 5^n+1. I used this to help with some homework and it didnt work with 5^n+1, but did work with 5^n even with n=0...

[@mathwithprofessorv]

No, you’re incorrect. I brought the 5 outside of the sum inside with 5^n, making it 5^(n+1).

[@Sanda.iTUBEvideos]

❤

[@morenoclr]

10:14

[@santaclaus2480]

Isn’t there an error in q 3? Shouldn’t the distribution of( 2^4)^(n+1) be 2^(4n+4) not 2^(4n+2)?

[@mathwithprofessorv]

Yes, I addressed it in a comment a while back but now I pinned it so everyone can see. Good catch!
