Tag: quadratic
Simple mathematical operation program written in C++ (simple operation program source code for common factors, average values, linear functions, quadratic functions, etc.)
After we learn the simple loop structure of cpp, we can create operations on common factors, common multiples, and average values. #include <bits/stdc + + .h> using namespace std; int main(){ cout<<“First enter 1 or 2 to represent the number of numbers, then press Enter and then enter the number (positive integer), all its common […]
Optimization method Python calculation: non-quadratic conjugate gradient algorithm

chatgpt empowers python: How to write a quadratic equation in one variable in Python?
How to write a quadratic equation in one variable in Python? Quadratic equations in one variable are a common occurrence in high school mathematics. However, sometimes we need to use computers to solve practical problems, and we also need to solve quadratic equations in one variable through code. This article shows how to write code […]
chatgpt empowers python: Python writes quadratic equation formula in one variable
Python writes quadratic equation formula In mathematics, a quadratic equation of the form is a x 2 + b x + c = 0 ax^2 + bx + c=0 The equation for ax2 + bx + c=0, where x x x is unknown, a , b , c a,b,c a,b,c are known constants, and a […]
chatgpt empowers python: Python uses functions to find the root of the quadratic equation
Python uses functions to find the root of the quadratic equation Introduction Python is a high-level programming language with powerful data processing capabilities and a wide range of application scenarios. Functions in Python are very important concepts, through which code can be organized into a modular structure to achieve more efficient programming and code reuse. […]
RANSAC principle and quadratic/cubic polynomial curve fitting
RANSAC principle RANSAC (RANdom SAmple Consensus) is a classic model fitting algorithm used to find the best model from a set of messy data. Its basic idea is to randomly select a certain number of data points, use these data points to fit the model, and then bring all the data points into the model, […]
Python: Solve quadratic equations in one variable (with fractions and root results) 2.0X
The previous function of solving equations can produce integers, fractions, and results with root signs, but there will be a small bug, that is, there will be strange results similar to 2/2. Solving equation 1.0X solves the root while improving this result. The number under the number also has the number of divisible roots that […]
