11.)Show that the central angle subtended by a chord is twice the angle of an inscribed angle subtended by the same chord when the centre of the circle is outside the inscribed angle. (This is case 2 for Circle Angle 1)Hint: Draw the diameter from C.O2ai AB ...

Arc Length = (Degree Angle/360) x 2π x Arc Radius If you calculate the arc length using radians, the process is a bit simpler. Since a radian value is a fraction of 2π, and we need to multiply by 2π in order to calculate the arc length, the two cancel out. We are left wit...
The solid angle subtended by a circle of radius R with respect to any point is calculated. The solid angle is expressed as a function of the inclination angle θ from the central normal to the circle and the distance λR from the center of the circle. The result is given in terms of ...
The Chaps. 10 and 11 of Book I of the Almagest contain the ancient theory of plane trigonometry and the resulting tables. The basic function, however, is not the sine function but its equivalent, the length of the chord subtended by the given angle in th
He showed by using geometric construction and the law of refraction (also known as Descartes's law in France, or more commonly Snell's law elsewhere) that the angular radius of a rainbow is 42 degrees (i.e., the angle subtended at the eye by the edge of the rainbow and the ray ...
To prove that the angle subtended by an arc of a circle at the center is double the angle subtended by it at any point on the remaining part of the circle, we will consider two cases: when the arc is a minor arc and when it is a major arc.<stro
