Constructive framework available for the study of trigonometric relations

摘要

Constructive framework available for the study of trigonometric relations, the utility model is a constructive framework available for the study of trigonometric relations.Located in the technology sector of equipment for teaching and research, and facilitates the presentation of the trigonometrical relationships, allowing the study of the degree, radian, quadrants.Sine, cosine, tangent, trigonometric circle, among others, supporting the work of the educational process.Currently, there is no equipment that allows the teacher presents the study of trigonometry in a practical way and objective.Requiring that has to make drawings in black or white to demonstrate the trigonometrical relationships; and the quality of teaching and the time of completion of each class.What complicates the learning process.It is characterized by a panel (1) provided centrally of a laminar element is translucent and prone to cute (11); and,Fitted centrally a circular element (3) with a central vertical axis (4), a horizontal central axis (5) and (6), the vertical tangent with scale values (6a).And inside are dashed lines vertical frames (7) and horizontal (8), with notes of trigonometric values, and indication of quadrants IQ.
