What is the probability that a plant chosen at random will be will be between 20.5 and 25.5 cm tall? Mathematics Looking for something else? Not the answer you are looking for? Search for more ...
Repository URL: Author(s): Craig Callender ##### preprint description A persistent question about the deBroglie–Bohm interpretation of quantum mechanics concerns the understanding of Born’s rule in the theory. Where do the quantum mechanical probabilities come from? How are they to be interpreted? These are the problem...
1. ## continuity problem (domain) Hello, I don't understand why the answer for the domain is wrong. Can anyone tell me the correct answer? Thank you. 2. ## Re: continuity problem (domain) $Q(x)$ isn't defined for $x = \sqrt[3]{3}$ therefore the domain of $Q(x)$ is $(-\infty, \sqrt[3]{3}) \cup (\sqrt[3]{3},\infty)...
# Funny identities Here is a funny exercise $$\sin(x - y) \sin(x + y) = (\sin x - \sin y)(\sin x + \sin y).$$ (If you prove it don't publish it here please). Do you have similar examples? - Maybe a moderator should put the zeta ones together since there are three already? –  anon Nov 3 '10 at 22:29 Perhaps this shoul...
• 0 Custom Quests Lists (bad argument #1 to 'ipairs') Question I vaguely remember a thread about the exact same issue I'm facing these days, but I can't find it using either the forum's search engine or Google, so I apologize in advance if this was already answered somewhere else. My problem, however, is not only th...
# Real-Time Robotics Framework ### Sidebar getting_started:tutorials:oneaxis # Control a Single Motor This tutorial will show you how to control a single motor using EEROS.

# Relationship between Coefficients of Orthogonal Polynomial and Normal regression So this is more a question to help me understand what is going on rather than application: So in normal regression we have $$\mathbf{Y=X} \mathbf{\beta} + \varepsilon$$ Now the part that really confuses me: A regression with orthogo...
# Problem 23 Chapter 2. Evans PDE 2nd edition This is a Problem from Evans PDE 2nd Edition,Chapter 2 Problem 23. Let $S$ denote the square lying in $\Bbb R\times (0,\infty)$ with corners at the points $(0,1),(1,2),(0,3),(-1,2)$. Define $$f(x,t):=\left \{ \begin{array}{ll} \ -1, \text{ for } (x,t)\in S\cap \{ t>x+2\} \...
