Corbettmaths – This video shows how to solve inequalities with a single inequality sign.
The Triangle Inequality for vectors is |a+b|≤|a|+|b|. (a) Give a geometric interpretation of the Triangle Inequality. (b) Use the Cauchy-Schwarz Inequality from Exercise 61 to prove the Triangle Inequality.

What might it feel like to invent calculus? Brought to you by you: http://3b1b.co/eoc1-thanks Home page: https://www.3blue1brown.com/ In this first video of the series, we see how unraveling the nuances of a simple geometry question can lead to integrals, derivatives, and the fundamental theorem of calculus. —————— These animations are largely made using manim, a…
