Specific resistance
Conductor ampacity rating is a crude assessment of resistance based on the potential for current to create a fire hazard. However, we may come across situations where the voltage drop created by wire
resistance in a circuit poses concerns other than fire avoidance. For instance, we may be designing... | 4 | [

A toy model for the t-section problem

Let $S(x)$ be the area of the yellow curvilinear triangle. I'd like to find a graph for which $S(x)=H(x)$ where $H $ is some prescribed function (small, smooth, vanishing near the endpoints to any
order you wish, etc.). Is it always possible or there... | 4 | [

Regression 1 – All possible regressions of the Hald data
Introduction
Well, I’ve been battering you with mostly theory. I’ve shown you all of the properties that Mathematica® can provide for a regression… and I’ve shown you how almost all of them are computed.
Not content with that large collection of properties, I t... | 4 | [

Complex Numbers: Graphing Functions with Imaginary Numbers

From: Carolyn
Subject: Graphing functions with imaginary numbers
My pre-calculus class was graphing the function f(x)=x^(2/3) on our
graphing calculators, and my teacher asked us for the domain of the
function. We all agreed that... | 5 | [
