Use calculus, NOT calculators!

We will use a tangent line approximation and differentials to approximate sqrt(8.7). This is called local linear approximation, an application of derivatives in Calculus 1. 0:00 use tangent line approximation for sqrt(8.7) 4:49 use differentials to approximate sqrt(8.7) Ask me calculus on Threads: https://www.threads.net/@blackpenredpen ----------------------------- 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
