Virtual manipulatives for mathematics are digital representations of physical mathematics manipulatives used in classrooms. [1] The goal of this technology is to allow learners to investigate, explore and derive mathematical concepts using concrete models.
C.a.R.– Compass and Ruler (also known as Z.u.L., which stands for the German "Zirkel und Lineal") — is a free and open source interactive geometry app that can do geometrical constructions in Euclidean and non-Euclidean geometry. The software is Java based. The author is René Grothmann of the Catholic University of Eichstätt-Ingolstadt.
A virtual politician would have similar power to a human serving in the same position, but would be programmed to make choices based on an artificially intelligent algorithm. Since the dawn of AI , machines have been put to work in various positions formerly held by humans for different reasons; repetitive tasks, or else to lighten the workload ...
Each ruler's scale has graduations labeled with precomputed outputs of various mathematical functions, acting as a lookup table that maps from position on the ruler as each function's input. Calculations that can be reduced to simple addition or subtraction using those precomputed functions can be solved by aligning the two rulers and reading ...
Using a markable ruler, regular polygons with solid constructions, like the heptagon, are constructible; and John H. Conway and Richard K. Guy give constructions for several of them. [20] The neusis construction is more powerful than a conic drawing tool, as one can construct complex numbers that do not have solid constructions.
The Kingdom of Eswatini is a diarchy in which the King rules in conjunction with his mother, the queen mother in their capacity as traditional rulers. Constitutionally, however, the King is the sole head of state, though it is often argued that the giving of authority wholesale to the royal male in this way is a neo-traditionalistic as opposed ...
A titular ruler, or titular head, is a person in an official position of leadership who possesses few, if any, actual powers. [1] Sometimes a person may inhabit a position of titular leadership and yet exercise more power than would normally be expected, as a result of their personality or experience.
The feature set includes tools for drawing, shapes and media. Drawing in Microsoft Whiteboard is called inking. It works both on mobile devices and computers. The inking toolbar has customizable pencils, as well as a ruler, a highlighter, an eraser and an object selector. Whiteboard can recognize shapes drawn by hand and straighten them.
