Σελίδα 80 - I. The sine of the middle part is equal to the product of the tangents of the adjacent parts.
Σελίδα 74 - Therefore cos a = cos b cos с + sin b sin с cos A. Hence in any spherical triangle cos a = cos b...
Σελίδα 70 - The sum of the angles of a spherical triangle is greater than two and less than six right angles ; that is, greater than 180° and less than 540°. (gr). If A'B'C' is the polar triangle of ABC...
Σελίδα 68 - A tangent to a circle is perpendicular to the radius drawn to the point of contact.
Σελίδα 6 - This angle is said to be in the first, second, third, or fourth quadrant according as the terminal line OP falls in one or other F1G.
Σελίδα 74 - ... cos a = cos b cos с + sin b sin с cos A ; (2) cos b = cos a cos с + sin a sin с cos в ; ^ A. (3) cos с = cos a cos b + sin a sin b cos C.
Σελίδα 196 - The logarithm of the quotient of two numbers equals the logarithm of the numerator minus the logarithm of the denominator.
Σελίδα 86 - In addition to these four cases we shall find that, when given two sides and an angle opposite one of them, or two angles and a side opposite one of them...
Σελίδα 3 - ... generally, Analytical Trigonometry. This subject is a large one, and has close connections with many other branches of modern mathematics. The system of angular measurement now to be described, is sometimes referred to as the theoretical system of measurement. In this system the unit angle is the angle which at the centre of a circle subtends an arc equal in length to the radius. This unit angle is called a radian. Thus, if a circle with any radius be described about 0 as a centre, and an arc...
