Description

Have you ever wondered what Quadratics areallabout?

This app enables you to visualise graphically what happenswhenyou change the values of a, b and c in the quadratic equation y=ax² + bx + c. Generally the shape of the graph is a parabola.Butis it always parabolic? Where does it cross the x and y axes –ifat all? Where is the vertex – if there is one? This andotherquestions can be answered using this app.
The main features of the app are:
* An interactive approach to help deepen understanding ofQuadraticEquations
* Visualising the quadratic equation and its x/y interceptsandvertex graphically
* Zoom in/out graphically
* On-screen take-by-the-hand walkthrough to helphighlightinteresting mathematical features
* A Quadratic Calculator to calculate the x/y intercepts,vertex,factored and vertex forms of the quadratic from chosenvalues fora, b and c (for real values).

Keywords: quadratics, trinomial factoring, graphvisualisation,parabola, algebra, GCSE, college, math, mathematics,GRE, SAT,ACT

TeachMe Simultaneous Equations 1.0 APK
PointKinetic
Have you ever wondered what LinearSimultaneous Equations (LSEs) are all about?When you solve these equations, what does the solution mean? Didyou know that these equations and straight line graphs are related?You might already know the equation of the straight line, y = mx +c (as seen in the TeachMe Linear Equations app). TeachMeSimultaneous Equations enables you to visualise graphically whathappens when you change the values of a, b and k in a pair of LSEsin the form ax + by = k. In many cases the straight line graphsintersect - this point of intersection is important whenconsidering linear simultaneous equations. But how? Sometimes theydon’t intersect at all. In which case, how does this relate to thesolution? These and other questions can be answered using thisapp.The main features of the app are:* An interactive approach to help deepen understanding of LinearSimultaneous Equations and how to find their solutions.* Highlight where the point of intersection occurs.* On-screen take-by-the-hand walkthrough to help highlightinteresting mathematical features, including how to manually solvethe equations.* A Maths Calculator that provides comprehensive informationrelating to the simultaneous equations and their graphicalinterpretation, with the ability to solve manually enteredequations.KEYWORDS: linear simultaneous equations, algebra, straightlines, graphical visualisation, interactive learning, teaching,tablet, learning mathematics, maths, math, y=mx+c, ax+by=k,college, GCSE, GRE
