Seite 59 - Root of a Number: Divide the logarithm of the number by the index of the root ; the quotient is the logarithm of the required root of the number.
Seite 24 - All the interior angles of any rectilineal figure, together with four right angles, are equal to twice as many right angles as the figure has sides.
Seite 25 - The angle at the centre of a circle is double the angle at the circumference on the same arc.
Seite 57 - If the given number is greater than 1, make the characteristic of its logarithm one less than the number of figures to the left of the decimal point in the number.
Seite 88 - The logarithm of any power of a number is equal to the logarithm of the number multiplied by the exponent of the power.
Seite 25 - The angles in the same segment of a circle are equal to one another.
Seite 21 - Therefore, the specific gravity of a solid or a liquid body is the ratio of its weight to the weight of an equal volume of water...
Seite 26 - ... the square on the hypothenuse is equal to the sum of the squares on the other two sides.
Seite 244 - The change in motion is proportional to the applied force, and takes place in the direction in which the force acts.
Seite 14 - Quantities are said to be in continued proportion when the first is to the second, as the second is to the third, as the third to the fourth ; and so on.
