I’ve been trying to figure this out for days. I hope I can explain this clear. I am trying to call up the results of this simple math equation in JavaScript code below: <?php $x=37; $y=15; $z=$x-$y; echo " ",$z; ?> part of the script code { y: $z, label: "slice" }, { y: 2,… Read More Trying to put a PHP math result into JavaScript chart
I’m trying to put the results of this simple JavaScript into a div, where i put the results anywhere on the webpage Example script: var numOne=25 , numTwo=14 , res ; res = numOne – numTwo; document.write(" " + res + ""); I don’t have a clue how to set this up in the script… Read More Is it possible to use a JavaScript in simple math equation but place results in a div
I’m truly a newbie at any of this. Anyway, I’m trying to put the results of this simple JavaScript into a txt file Example script: var numOne=25, numTwo=14,res; res = numOne – numTwo; document.write(” ” + res + “”); I want to create a txt file and put the results in it, instead of showing… Read More Is it possible to use a JavaScript in simple math equation but place results in a text file?
I want to emulate this in LaTeX code as an equation. \usepackage{spalign} \[ \spalignsys{ \text{Maximizar} \hspace{4mm} z=c_1x_1+c_2x_2+\dots+c_nx_n ; \text{Sujeto a:} ; \hspace{4mm} a_{11}x_1+a_{12}x_2+\dots+a_{1n}x_n \leq b_1; x_1,x_2,\dots,x_n \geq 0 } \] >Solution : You can use the same technique as in https://tex.stackexchange.com/a/587258/36296 : \documentclass{article} \usepackage{amsmath} \begin{document} \[ \left\{\begin{array}{lc} \text{Maximizar} & z=c_1x_1+c_2x_2+\dots+c_nx_n\\ \text{Sujeto a:}& \\ &a_{11}x_1+a_{12}x_2+\dots+a_{1n}x_n \leq… Read More SIMPLEX system of Latex equations
I want to calculate complex eigenvectors (Psi functions for shrodinger equation) for 20k*20k matrices, but always gets smth like this: [ 2.99009782e-09 -1.12381299e-08 -2.82346868e-08 …, 6.20967928e-34 -4.80675528e-34 -3.84848719e-35] [ 4.07337553e-08 -1.45976681e-07 -3.47961439e-07 …, 7.43558322e-34 -5.74815572e-34 -4.61317607e-35] [ 5.51921102e-07 -1.88491289e-06 -4.26000711e-06 …, 9.29535407e-34 -7.15304083e-34 -5.78846547e-35] As I understand it just replaces part of data with dots,… Read More eigenvectors created by numpy.linalg.eig have dots instead of data
I am trying the write something below in latex and what I am trying seems not working well. \documentclass[10pt,english,8pt]{beamer} \usepackage{amsmath} \begin{document} \begin{frame} \begin{itemize} \item Observation equation: $\begin{pmatrix} PD_{s,t}\\ RR_{s,t} \end{pmatrix} = \binom(\gamma_{1}\gamma_{2}) = bla \end{itemize} \end{frame} \end{document} >Solution : The syntax \binom(…) is wrong. \binom is a macro with two mandatory arguments, so you need… Read More combination/matrix in latex
I’m solving an time depend equation that has the following form (finding the roots for \lambda): import sympy as sp import matplotlib.pyplot as plt t = sp.symbols(r’t’, real=True, positive=True) eq = … print(repr(eq)) -\lambda**3 – 2*\lambda**2*t + 4*\lambda*t**4 – 8*\lambda*t**3 + 8*\lambda*t**2 – 8*\lambda*t + 4*\lambda + 8*t**3 – 16*t**2 + 8*t Solving the equation… Read More Mixing solutions of sympy equation
I am trying to figure out how to plot the decision boundary line picking just few middle values instead of the entirety of the separator line such that it spans roughly the y-range that also the observations span. Currently, I manually repeatedly select different bounds and assess visually, until "a good looking separator" emerged. MWE:… Read More Plotting class decision boundary: determine a "good fit" range directly
After i get pass 20 on the user end my if/else doesn’t pick up the next variation of the equatuion. I know its because of setting the total = (numberofchecks * twentychecks) + (fee); but i can’t figure out what to use to get it to move to the next variation of the equation. The… Read More How can i get this equation to work within this nested if/else statement for c#?
Picture 50 rows that all have a number "4" in it. However in each row there are 26 columns (A-Z) and the 4 is placed on a different letter in each row. I need a count of finding the "4" in each row (i.e. if it’s "E" that the "4" sits in, the count should… Read More Excel: Count sum of cells along a row until a value is found
