We introduce the definition of the neighborhood of a point and show how the definition of the limit of a sequence can be rewritten in terms of neighborhoods. The concept of a neighborhood is important, so it's handy to have this convenient language and notation to describe it. We'll also see examples of neighborhoods visually. #realanalysis Open Sets: https://youtu.be/pnWgj8jjs3w Thanks to Crayon Angel, my favorite musician in the world, who upon my request gave me permission to use his music in my math lessons: https://crayonangel.bandcamp.com/ Follow Wrath of Math on... ● Instagram: https://www.instagram.com/wrathofmathedu ● Facebook: https://www.facebook.com/WrathofMath ● Twitter: https://twitter.com/wrathofmathedu
