Abstract
The utility model relates to a multifunctional mathematic ruler. Rulers, set squares, protractors and compasses those conventional drawing tools are necessary in mathematic drawings, and drawing tools should be continually changed when certain geometric drawings are drawn, so that the process is not convenient. The multifunctional mathematic ruler comprises a main ruler (1), wherein two ends of the main ruler are fixedly connected with a 90-degree protractor respectively; two ends of the main ruler are respectively connected with a semicircular cambered slipway (3); an auxiliary ruler (6) is arranged on each slipway through a rivet (4) behind the auxiliary ruler; the auxiliary ruler and the main ruler are hinged together through a flexible material; and two ends of the auxiliary ruler are connected with a pointer (5). The multifunctional mathematic ruler is used for mathematic drawing.
Description
Technical field:
the utility model relates to a kind of multifunctional mathmatical ruler.
Background technology:
are present; The ruler that people use has meter ruler, ruler, set square, tape measure, tape measure, T-square etc., but the most function singleness of these rulers, has satisfied not the needs of mathematical education and study; Relate in particular to trigonometric function; The student is through tabling look-up or use the method for calculator to obtain the value of trigonometric function, making learning process more uninteresting, inadequately image basically.
The utility model content:
The purpose of
the utility model is the multifunctional mathmatical ruler that the problem to above-mentioned existence provides a kind of low price, is convenient for carrying; When possessing general mathmatical ruler function, can also solve the relevant problem of Pythagorean theorem, sine, the cosine law.
Above-mentioned purpose realizes through following technical scheme:
multifunctional mathmatical ruler; Its composition comprises: main scale; The two ends of described main scale are fixedly connected the protractor at 90 ° of angles respectively, and the two ends of described main scale connect semicircular cambered way respectively, and secondary chi is installed on the described slideway through the rivet of back; Hinged between described secondary chi and the described main scale through flexible material, the two ends concatenation pointer of described secondary chi.
described multifunctional mathmatical ruler, described main scale is 10 centimetres a ruler, is divided into 100 five equilibriums, whenever is divided into 1mm.
Beneficial effect:
1. the utility model except that the function that possesses general ruler and protractor; Special feature is directly to read trigonometric function value, checking Pythagorean theorem, sine, the cosine law; Also have the compasses function concurrently, and the circle of known radii that can draw fast.For convenient reading, the utility model can directly be read angle at two secondary chi two ends concatenation pointers.
Description of drawings:
accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment:
Embodiment 1:
multifunctional mathmatical ruler; Its composition comprises: main scale 1; The two ends of described main scale are fixedly connected the protractor 2 at 90 ° of angles respectively, and the two ends of described main scale connect semicircular cambered way 3 respectively, and secondary chi 6 is installed on the described slideway through the rivet 4 of back; Hinged between described secondary chi and the described main scale through flexible material, the two ends concatenation pointer 5 of described secondary chi.
Embodiment 2:
described multifunctional mathmatical ruler, described main scale is 10 centimetres a ruler, is divided into 100 five equilibriums, whenever is divided into 1mm.
To read the method for using that trigonometric function value is example explanation the utility model:
are hypotenuse with the main scale, and length is 10 centimetres, and the angle of the first secondary chi and main scale is the trigonometric function value that will read.Rotate the first secondary chi earlier; The angle that makes win secondary chi and main scale is the size at the angle of giving; And then rotate the second secondary chi; Make the second secondary chi vertical with the first secondary chi, at this moment the reading of the first secondary chi with the result of decimetre office be exactly institute to the cosine of an angle value, the reading of the second secondary chi is exactly the sine value at the angle of giving with the result of decimeter office.
Claims (2)
1. multifunctional mathmatical ruler; Its composition comprises: main scale; It is characterized in that: the two ends of described main scale are fixedly connected the protractor at 90 ° of angles respectively, and the two ends of described main scale connect semicircular cambered way respectively, and secondary chi is installed on the described slideway through the rivet of back; Hinged between described secondary chi and the described main scale through flexible material, the two ends concatenation pointer of described secondary chi.
2. multifunctional mathmatical ruler according to claim 1 is characterized in that: described main scale is 10 centimetres a ruler, is divided into 100 five equilibriums, whenever is divided into 1mm.
