Have you ever wondered what Linear Simultaneous Equations (LSEs) are all about?

When you solve these equations, what does the solution mean? Did you 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). TeachMe Simultaneous Equations enables you to visualise graphically what happens when you change the values of a, b and k in a pair of LSEs in the form ax + by = k. In many cases the straight line graphs intersect - this point of intersection is important when considering linear simultaneous equations. But how? Sometimes they don’t intersect at all. In which case, how does this relate to the solution? These and other questions can be answered using this app.

The main features of the app are:
* An interactive approach to help deepen understanding of Linear Simultaneous Equations and how to find their solutions.
* On-screen take-by-the-hand walkthrough to help highlight interesting mathematical features, including how to manually solve LSEs.
* A Maths Corner provides comprehensive information relating to the LSEs and their graphical interpretation.

KEYWORDS: linear simultaneous equations, straight lines, graphical visualisation, interactive learning, learning mathematics, maths, math, y=mx+c, ax+by=k, college, GCSE

Have you ever wondered what Linear Equations are all about?
This app enables you to visualise graphically what happens when you change the values of m and c in the linear equation y = mx + c. The shape of the graph is a straight line. But is it always a straight line? Where does it cross the x and y axes – if at all? This and other questions can be answered using this app.
The main features of the app are:
* An interactive approach to help deepen understanding of linear equations
* Visualising the linear equation and its x/y intercepts graphically
* Zoom in/out graphically
* On-screen take-by-the-hand walkthrough to help highlight interesting mathematical features
* A Maths Corner to calculate properties of a linear equation from chosen values for m and c.

Keywords: Straight line, linear equations, interactive learning, math, mathematics, graphical visualisation, GCSE, college

TeachMe Quadratics (v. 1.0)

Have you ever wondered what Quadratics are all about?

This app enables you to visualise graphically what happens when you 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. But is it always parabolic? Where does it cross the x and y axes – if at all? Where is the vertex – if there is one? This and other questions can be answered using this app.
The main features of the app are:
* An interactive approach to help deepen understanding of Quadratic Equations
* Visualising the quadratic equation and its x/y intercepts and vertex graphically
* Zoom in/out graphically
* On-screen take-by-the-hand walkthrough to help highlight interesting mathematical features
* A Quadratic Calculator to calculate the x/y intercepts, vertex, factored and vertex forms of the quadratic from chosen values for a, b and c (for real values).

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