This computer calculates the chord length of a circle, arrow quantity, a radius, an angle, etc. using trigonometric functions. It corresponds also to chord length calculation of a special circle with a straight line. - In RH computer mode, chord length (W) and a radius (R) to calculation or arrow quantity (H) is [ a radius (R) ] computable from chord length (W) and arrow quantity (H). - In W computer mode, calculation, or arc length (L) to a radius (R) and chord length (W) is [ chord length (W) ] computable from a radius (R) and an angle (theta). Furthermore, in this mode, it can be chosen as the both ends or one side of a circle from the figure of eight patterns to which the straight line was attached, and can ask for chord length (W). * Thickness is given to a circle and a straight line and the chord length (W) of an inner R side and each outside R side is called for. (It contains in eight patterns)
