So I was trying to understand Horner's method. I understand that you can take a polynomial and factor out the x's and re write it as multiple linear functions recursively plugged into each other and that this makes evaluating a polynomial easier because you just evaluate a linear function...
They are mysterious to me, they do not make any intuitive sense. What is the context for them? I found this website. http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/cfINTRO.html
It tries to show the history of how they were discovered geometrically. So you start off with a...
I was watching this video about how they invented log tables and some things I do not understand.
At 5:12 he changes the scaling from 1's to 10's I don't understand how this is allowed. The number represents the number of times the base was multiplied by itself. In the seconds before this...
In case you have not seen the equation that has gone viral recently https://www.popularmechanics.com/science/math/a28569610/viral-math-problem-2019-solved/
This lead me to this
Why are physicists allowed to break the rules? What reasoning does the Physics Review and Feynman have for making...
Intuitively I fell like AC would lose more power long a long power line than DC. I will use a model to explain my perspective.
Let me model a wire as a long straight, non-frictionless tube, about the diameter of a marble, filled with a row of marbles that are each connected to the one next to...
I know the answer, because they are not grounded and do not complete any circut, but I have a different analysis that I would like to explore.
First, why do you need a closed circuit? Because if you have a battery pushing current along a wire that ends, electrons will accumulate at the end of...

For part A i figured it must be E because that is the only one that goes to 0 as the hit says.
but nothing about this problem makes any sense to me.
