While playing with quadratic forms in Sagemath 10.7, I came across this specific error: sage: version() 'SageMath version 10.7, Release Date: 2025-08-09' sage: t = 8 sage: B = matrix(ZZ, [(1, 0, 0),(1,...

I would like to solve this system of equation for X and Y : Do you know if their exist a mathematical solution to this system ? And how to solve it ? Or a numerical solution ? If yes, do you think ...

My goal is to create a C++ program that computes a geometric sequence's first three terms. What is provided is the sum of the first three terms and their multiplication. It is assumed that the answers ...

I have a vector of values 0-100. values <- runif(n = 1000, min = 0, max = 100) I'd like to transform these values into a concave down parabolic curve where values at the middle (approximately 50) ...

I've been trying to calculate the discriminant of a quadratic equation. Though, I decided to use regex, so the user could put the entire equation instead of the information repeated times. The code ...

For a homework question we have been asked to numerically find the estimated roots of a quadratic equation ax^2 + bx + c, (where a, b, c is given by the user), we cant use the -b formula and we have ...

I am trying to plot an interaction between a squared variable and a dummy from a multi-level logistic regression in R. Whilst I have no problem plotting these interactions with a non-quadratic ...

I have the start and end point of the curve and the top point of the curve. I would like to know how i can get the control point with this ? I have a graph with links. When a link is on a node, i want ...

here is my code. Can anybody help to solve the problem? In the code below everything what I made but it doesn't work. def read_equation(textfile: str) -> str: with open(textfile, 'r') ...

I'm using the ROI package in R and am trying to setup an optimization with a quadratic objective function. It looks like the default function is of the form: 1/2 x^T Q x+ C^T x. I'd like to alter this ...

I am looking for a way to score model fits of x,y data on a scale from 0 to 1, depending on which model the data best fit. If data fit a linear model best, the score would come out close to 1. Log ...

I am working with a program that defines its Curves with 'Edges' that have three control points (The red points 0, 1, 2 in the attached image). I believe this is a Quadratic Curve. This is a list of ...

Here's my code. import math print('I will solve the equation ax^2=bx=c=0') a = int(input('a= ')) b = int(input('b= ')) c = int(input('c= ')) d=b**2-4*a*c if d < 0: print('The equation has ...

I'd like to draw linear and quadratic regression line per group (data is different). For example, I make a graph like below. x=rep(c(0,40,80,120,160),time=2) y=c(16,21,22,26,35,29,44,72,61,54) group=...
