Page 224 - The squares of the periods of revolution of any two planets are proportional to the cubes of their mean distances from the sun.
Page 92 - ... the tangent of the angle which the line makes with the axis of abscissae), was lately employed by M. Crova* for the discussion of experiments relating to the degree of constancy possessed by so-called
Page 132 - Art. 255); and the equation will become id \ i du a(lu) = le — , tv that is, the differential of the logarithm of a quantity is equal to the modulus of the system into the differential of the quantity divided by the quantity itself. 57. If we suppose a = e the base of the Naperian system, and employ the usual characteristic I...
Page 231 - A magnitude is said to be ultimately equal to its Limit; and the two are said to be ultimately in a ratio of equality. 4. A line or figure ultimately coincides with the line or figure which is its Limit.
Page 171 - Curve is ono whose equation contains transcendental functions. Many of the higher plane curves possess historical interest, from the labor bestowed on them by ancient mathematicians. We shall consider only a few of them. THE CISSOID OF DIOCLES. 148. This curve was invented by Diocles, a Greek geometer who lived about the sixth century of the Christian era; the purpose of its invention was the solution of the problem of finding two mean proportionals. It may be defined as follows : If pairs of equal...
