WebGeoGebra在二次函数学习中的作用. 作者：解新一. 来源：《软件导刊》2013年第03期. 摘 要：GeoGebra是一套结合几何、代数、数据表、图形、统计和计算的动态数学软件，功能十分复杂和庞大，用户不可能也没有必要掌握其所有功能，掌握几个特殊的指令，如Fitpoly、Extremum、PerpendicularLine、Root、Intersect等 ... WebA spline is as far I can see not an regular mathematic expression (like fitpoly[list, grade]), but could be a line between the point furthest left and the point furthest right and goes through al points. ... Edited to say -- while this works perfectly in the release version of Geogebra (3.0.4), the current beta of 3.2 really doesn't like it ...

Dựa theo mô hình hàm số bậc nhất f (x) = 0,02x + 1,96, ta dự đoán được tỉ lệ sinh của các năm 2024, 2024, 2024... lần lượt là: f (4) = 0,02 . 4 + 1,96 = 2,04; f (5) = 0,02 . 5 + 1,96 = 2,06; f (6) = 0,02 . 6 + 1,96 = 2,08. flowers apartments gaithersburg
How to make a parabola in GeoGebra? - Mathematics Stack …
WebFeb 11, 2014 · 1. A general conic in the plane is determined by 5 points on it. You can't make a parabola that pass through more than 5 arbitrary points. In GeoGebra, if you have 5 points, there is already a button that let you construct a conic out of them. – achille hui. WebIf you're familiar with FitLine, FitPoly, etc, then you have probably found out that there is a limited number of FitXxxxx variations. There is no FitCosh[] natively embed in Geogebra. By using Fit[], any kind of function that can be expressed as f(x) can be used as a basic function that will be adjusted to best fit to a list of points. WebSelect the cells, (as in any spreadsheet) and right click. Choose 'Create list of points'. In the algebra view you should have 'list1= {.....} and the points should be visible in the graphics view. In the input line: Fitpoly [list1,2] should give a quadratic f (x), visible in the algebra window and graphics view. green and white nfl team
