Description
Изобретение относитс к учебным прнt5opaM по тригонометрии.This invention relates to educational applications for trigonometry.
Известно учебное нагл дное пособие по тригонометрии, содержащее градуированный диск и установленные шарнирно на его оси стрелки {1 .A well-known educational aid on trigonometry, containing a graduated disk and arrows {1, pivotally mounted on its axis.
Недостатком его вл етс то, что оно не позвол ет нагл дно иллюстрировать все основные соотношени между тригонометрическими функци ми и их изменени в зависимости от аргументов во всех четвер-. т х.The disadvantage of it is that it does not allow to illustrate all the basic relations between the trigonometric functions and their changes depending on the arguments in all fours. mx
Целью изобретени вл етс повышение нагл дности иллюстрации основных соотношений тригонометрических функций и их изменений в зависимости от аргументов во всех четверт х.The aim of the invention is to increase the consistency of the illustration of the basic ratios of trigonometric functions and their changes depending on the arguments in all quarters.
Это достигаетс тем, что в предлагаемом приборе диск имеет жестко укрепленные вдоль осей X и Y магнитные пластинки, а на конце каждой стрелки установлен зажим , ролик и перекинутый через ролик эластичный элемент, имеющий на концах ферромагнитные указатели.This is achieved by the fact that in the proposed device the disk has magnetic plates rigidly fixed along the X and Y axes, and at the end of each arrow there is a clamp, a roller and an elastic element thrown over the roller, having ferromagnetic pointers at the ends.
На фиг. 1 изображен предлагаемый учебный приборг на фиг: 2 - то же, вид сбоку.FIG. 1 shows the proposed training device in FIG. 2: the same, side view.
Прибор содержит подставку .1, шарнирно соединенные с осью диска два стержн 2, зажим 3 дл креплени на заданном угле, ось 4 зажима, градуированный диск 5, две «магнитные пластинки 6, ферромагнитный указатель 7, эластичный элемент 8, перекинутый через ролик 9, общую ось 10 прибора, на которой подвижно установлены стержни 2, устанавливаема на ось зажима 1 i пружина замка, закрепленный конец 12 пружины зажима.The device contains a stand .1, two rods 2 pivotally connected to the disk axis, a clip 3 for fastening at a given angle, a clamp axis 4, a graduated disk 5, two magnetic plates 6, a ferromagnetic pointer 7, an elastic element 8 slung over the roller 9, the common axis 10 of the device, on which the rods 2 are movably mounted, is mounted on the axis of the clamp 1 i the lock spring, the fixed end 12 of the clamp spring.
Устройство работает следующим образом .The device works as follows.
Подставку I устанавливают так, чтобы градуированный диск 5 был обращен к обучаемым . Затем, использу зажим 3, освобождают стержень 2 от закреплени его с градуированным диском, при этом открепл ют одновременно ферромагнитные указатели 7 от магнитных пластин 6. Враща стержень 2 до объ сн емого углового значени , закрепл ют его на градуированном диске зажимом 3, а ферромагнитные указатели 7 устанавливают перпендикул рно ос м X и Y на магнитных пластинах 6, использу сеточную разграфку диска.The stand I is set so that the graduated disk 5 faces the trainees. Then, using clamp 3, the rod 2 is released from fastening it with a graduated disk, while simultaneously removing the ferromagnetic indicators 7 from the magnetic plates 6. Rotate the rod 2 to an explained angular value, fix it on the graduated disk with a clip 3, and the ferromagnetic Pointers 7 install perpendicular to the axes X and Y on the magnetic plates 6 using a grid disc graph.
