Interval of convergence of a power series. Reddit calculus 2 r/calculus

We are given the radius of convergence of a power series 5. How do we find the interval of convergence of this power series? This is definitely one of the hardest topics in Calculus 2 but let me help you master the concept! Subscribe to @bprpcalculusbasics for more Calculus 2 tutorials.

Oh. Watching you teach exposed a minor thing I can change about my delivery to make a massive improvement in students understanding me. When we’re walking through a problem I should be jotting little notes about why we’re doing each mini step (check the endpoints). I know I used to do that, and maybe I still do, but this is a reminder to me how helpful it is because your signposting lit up spots in my brain. Also it will organically slow me down to give breathing room.
Love your multiple channels!

Great video! I'm using these videos to brush up on my long-forgotten Calculus 2 while I pursue the end of my bachelor's degree in math!

And just by the values at 0, 5 and 10, which are -∞, 0 and ln(2), you can have a good guess that the series is just ln(x/5) on (0, 10]. Which it actually is.

Can you please do arithmo geometric series

Where do you get that "magic" eraser? Do you have a link?

The redditor did ask "What did I do wrong?" though, and I have no idea where he got the inequality |x - c| < R. Anyone has any ideas?

Thank you for your great video. But, please stop hiding videos from the public. Your videos deserve *MORE* exposure.
