The layout of mathematical expressions is improved - you can use Greek symbols, multiple or nested subscripts in labels, and other mathematical notation.Mathematical italicization is used in labels, measurements, calculations, and equations.Text style and size on axis tick marks are adjustable.Expanded line weights, line strokes, and point sizes allow for age-appropriate sizing of objects.New nonlinear transformations can be defined and added to the Transform menu.Multiple transformations can be combined into a single custom transformation.Angles can be defined by two intersecting rays or segments, and can also be defined to be reflex angles greater than 180° or trigonometric angles (between –2π and 2π radians).Easily construct polygons and their interiors with the new Polygon tool.Choose a grid with trigonometric labels, create and listen to dynamic audible functions, and graph parametric functions.Construct entire families of functions and families of curves, parameterized either geometrically or numerically.Function plots and loci can be transformed and iterated, and intersections of function plots can be found.In blank space, you can handwrite text or circle parts of your sketch for emphasis or make a freehand drawing that you can then transform.Add clarity with angle markers, congruency marks, and parallel arrows.The Marker tool enhances presentations and facilitates the use of interactive whiteboards.Mouse over that Hot Text to highlight the referenced object.Simply click an object to insert its fully mathematically formatted notation (Hot Text) into a caption.Hot Text makes presentations clearer and more effective by dynamically linking captions and the objects they describe.Pictures can be reflected, rotated, dilated, attached to points, cropped to polygons, iterated, used in locus constructions, and more!.Import digital photographs or drag and drop images from a web page into a sketch.Engage students in learning by letting them import and transform any image.
