[0002] The calculation of vectors is one of the compulsory courses for modern students. For the synthesis and decomposition of vectors, to calculate the magnitude and direction of vectors in the case of non-special angles, you must first measure the relative angle of the two vectors, and then use the cosine law to perform calculations , the calculation is cumbersome, and for beginners, using the parallelogram rule to calculate the composition and decomposition of vectors on paper is not intuitive and vivid enough to make people understand slowly

Abstract

The invention discloses a multifunctional vector arithmetic unit capable of directly solving the size and direction of a vector to be measured. The multifunctional vector arithmetic unit comprises four measuring sides which are hinged end to end to form a quadrilateral; a group of opposite angles of the quadrilateral are hinged with a hypotenuse; scale marks and scale numbers are arranged on the measuring sides and the hypotenuse; the measuring sides and the hypotenuse are all telescopic rods; and a protractor is arranged at one end of the hypotenuse. During synthesis and decomposition operation of the vector, the measuring sides and the hypotenuse are adjusted to form a corresponding parallelogram according to the known conditions, so that the size and direction of the vector to be measured can be read directly from the scale numbers of the measuring sides and the hypotenuse. The multifunctional vector arithmetic unit is simple in operation, convenient in calculation and clear and visual in expression way, is very suitable to be used as a teaching tool and facilitates the understanding and learning of beginners.

Description

technical field [0001] The invention relates to a stationery, in particular to a multifunctional vector calculator for calculating vector synthesis or decomposition. Background technique [0002] The calculation of vectors is one of the compulsory courses for modern students. For the synthesis and decomposition of vectors, to calculate the magnitude and direction of vectors in the case of non-special angles, you must first measure the relative angle of the two vectors, and then use the cosine law to perform calculations , the calculation is cumbersome, and for beginners, using the parallelogram rule to calculate the composition and decomposition of vectors on paper is not intuitive and vivid enough to make people understand slowly. Contents of the invention [0003] The problem to be solved by the present invention is to design a multi-functional vector arithmetic unit that can directly calculate the magnitude and direction of the vector to be measured in view of the defic...
