A device whose output function is proportional to the derivative, or rate of change, of the input function with respect to one or more variables.



(also derivator or derivimeter), a device for determining directions of tangents and normals at particular points on arbitrary curves. The differentiator-triangle is most widely used. At the vertex of the right angle is a column with an optical system for the precise mounting of the device. An arc indicates the scale dividing the angle in degrees (protractor). Sleeves are fixed parallel to the legs of the right angle through which markings are made to construct the tangent or normal to the particular curve.
