Believe in calculus, NOT calculators!

Let's see how to use calculus to approximate the square root of a non-perfect square number! We will approximate sqrt(10) and sqrt(67) then we will see the idea behind my "happy face method" is just the local linear approximation. 0:00 how to approximate square root numbers 4:43 the idea: local linear approximation ----------------------------- Support this channel and get my calculus notes on Patreon: ? https://www.patreon.com/blackpenredpen Get the coolest math shirts from my Amazon store ? https://amzn.to/3qBeuw6 ----------------------------- #calculus #bprpcalculus #apcalculus #tutorial #math
