Page 75 - If, with a view to demonstrate any proposition, a certain point is supposed, by virtue of which certain other points are attained ; and such supposed point be itself afterwards destroyed or rejected by a contrary supposition ; in that case, all the other points attained thereby, and consequent thereupon, must also be destroyed and rejected, so as from thenceforward to be no more supposed or applied in the demonstration.
Page 34 - Hamlet with the part of the Prince of Denmark omitted, for so far I have said nothing whatever about technical education.
Page 10 - From (3) p b9 b tan0'= 2~b = 2Tb=2l but this is the trigonometrical tangent of the angle which the tangent to the curve at (a, b) makes with the axis of x. Hence the new axis of y ' is a tangent to the curve at the origm.
Page 85 - *=!* and by simply changing the axes, we have hence, the sub-tangent is equal to the modulus of the system of logarithms from which the curve is constructed. In the Naperian system M=l, and hence the sub-tangent will be equal to 1 = AE.

Show that the radius of curvature at any point of this locus is J of the length of the radius vector to the corresponding point on the original curve. for a plane curve, the upper or lower sign being taken according as the curve is convex or concave to the axis of x, The normal at the point P of the conic Zabx = Ьхг + ay1 meets the axis of x at G.

These Practical Measurements include Measures of Surface, Measures of Volume, Measures of Capacity, and Comparison of Weights and of Money. MEASURES OF SURFACE. 334. A Surface is that which has length and breadth without thickness. THE EECTANGLE.

Page 48 - ... the three components (two horizontal and one vertical) of the movement under investigation. In what follows we shall consider only the horizontal movements; the same arguments, however, may be applied to the case of vertical movements. Let us suppose a small horizontal platform to be moving parallel to the axis of X, and let it be required to determine the acceleration of this motion. On this platform an apparatus is mounted which can oscillate parallel to the same axis with a natural period,...
Page 1 - A more general definition of function is : // two or more variables are so related that to any given set of values comprising one and but one value for each of the variables except one of them there corresponds at least one value of the latter variable, each of the variables is said to be a function of all the others. Thus, if v be the volume of a parallelepiped, say a slab, and if /, b and / be respectively its length, breadth, and thickness, each of the four variables is a function of the remaining...
Page 84 - The value m, which depends upon the value of the base a, of the system of logarithms employed, is called the modulus of the system.
