Page 12 - Arithmetic is the foundation of the higher mathematics, such as mensuration, trigonometry, and geometry — "that branch of mathematics which investigates the relations, properties, and measurements of solids, surfaces, lines, and angles; the science which treats of the properties and relations of magnitudes.
Page 28 - Spot distortion would exist even if the target surface were spherical with a radius equal to the distance from the center of the deflection system to the screen.
Page 20 - ... 50.2656 circumference, which, divided by the lead (96), gives .5235. Consulting a table of natural tangents. we find that this amount represents an angle of 27 degrees 40 minutes. The angle of the smaller gear will be the same. If shafts are at other than right angles, this condition will change the angles of the teeth of spiral gears; and when the pitch diameters are alike and the numbers of teeth different, the angles will be different. It is customary to use racks in connection with spiral...
