## Crocodile Mathematics## de Crocodile ClipsCrocodile Mathematics es un software de modelación matemática muy fácil de usar, destinado a la enseñanza de geometría y cálculo en escuelas secundarias. La creación de modelos matemáticos es muy simple: basta con unir enlazar formas, números, ecuaciones y gráficas. Shapes are the basic building blocks in Crocodile Mathematics. You can use them to build a wide range of models. The Parts Pane is where you choose the shapes you want to add to your models. The shapes pane can also be used to include equations, numbers and graphs in your model. The shapes range from lines, circles and arcs, through triangles and squares, to regular and irregular polygons where you choose how many sides you want. Dragging corners or lines will alter the properties, but it will stay the same shape; for example, no matter how you alter it, an isosceles triangle will always have two equal angles, and a square will always have 4 equal sides. A "general" tab allows you to change the colour and transparency, dimensions, position, rotation and scale of your shape. You can make your shape spin about its centre, while the "connections button" lets you link it to other shapes.
**Enlargement** Preset enlargements are 2x and 0.5x, but you can also choose to type in whatever value you want.
**Reflection** The standard axes are y, x, y=x or y=-x, but you can also choose any gradient or intercept you want.
**Rotation** Again, there are predefined rotations of 90 and 45 degrees, but you can type in any values for the angle and centre of rotation.**Translation** Type in x and y values for a translation.
You can also define transformations freely using the matrix tool. This allows you to specify your transforms exactly. It also allows you to use shapes to provide a visual illustration of matrix arithmetic. You can also click on the transformed shapes, to work with them or to apply further transformations. You can also drag centre of a rotation or the axis of a reflection on-screen, allowing you to visually define the exact transform (or combination of transforms) you want.
You can plot a wide range of functions, from lines and parabolae to exponential, trigonometric and hyperbolic curves. It also lets you choose the scales and sizes of the axes - you can choose specific ones for specific functions, such as trigonometric axes. Once you’ve chosen the nature of your function, use control points on the axes to change constants such as gradients and intercepts. The control points let you sweep through a range of values for constants, seeing how they affect the curve’s shape.
Once relations have been set up, you can choose which parameters they link. To do this, click on the relation arrow and choose the parameter you want from the menu which appears. The number part is linked to the equation in the same way, and can be used either as an input or an output. Using equations in this way allows you to use the shapes on-screen to provide visual demonstrations for abstract concepts. For example, you could investigate inverse proportionality by linking two shapes with an equation so that, as one is enlarged, the other shrinks.
Alternatively, number parts can be edited on-screen. This allows them to be used to input numeric values for the shape parameters to which they are linked. For example, you can use them to bring a number line to life, with shapes showing the relative positions of decimals or fractions. |
