Any chord to y 2 = 4ax which passes through the focus is called a focal chord of the parabola y 2 = 4ax. Let y 2 = 4ax be the equation of a parabola and (at 2, 2at) a point P on it. Suppose the coordinates of the other extremity Q of the focal chord through P are (at 1 2, 2at 1). Then, PS and SQ, where S is the focus (a, 0), have the same slope chord' chart Pronunciation: [key] a chart indicating by means of symbols the identity, sequence, and duration of the musical chords occurring in the accompaniment to a melody It's twice the length of the radius. This gives you our first math equation for the circle: D = 2 x R. Also, R = D/2. So the diameter is two times the radius and the radius is one half of the diameter. Circumference - The circumference is the distance around the circle. We use the following formula to figure the circumference: c = d * π The sharp (#) and the flat (b) are the two most common symbols. These are mostly positioned directly after the first letter in the chord name, but can also turn up on other places in the name. The sharp sign indicate that the tone is sharpened, meaning it is one semitone higher. C#, therefore indicate a sharpened C The chord of any circle is an important term. It is defined as the line segment joining any two points on the circumference of the circle, not passing through its centre. This article will explain the chord length formula with examples. Let us learn it

As you might know, chord construction can be, and is most often viewed in relation to major scales. For instance, any major chord is built by combining the 1, 3, and 5 (Root, 3rd and 5th tones) of its own major scale — like a G major chord contains the notes G, B, and D which are the 1, 3, and 5 of the G major scale Basically, a chord is comprised of 3 or more notes. Some disagree and say a chord can be made up using only 2, although that's usually called a dyad. Anyone marking this answer down due to that statement has a perfect right to explain why. Those 3 notes together get called a triad, and can be any 3 notes at all Theorem 1 : Perpendicular from the center of a circle to a chord bisects the chord. Given : A circle with centre O and AB is a chord of the circle other than the diameter and OC ⊥ AB. To prove : AC = BC. Construction : Join OA and OB The chord AB in the figure above defines one side of the segment. As you drag the points you will notice that the segment is always the smaller part of the circle. This is a definition of a segment. Its Central Angle is always less than 180° . In fact, if the chord divides the circle exactly in half (becoming a diameter) neither of the two halves are segments

Math Central: Quandaries & Queries: Question from Nicole, a student: What is a common chord between two circles and how is it found in the problem: Two circles intersect and have a common chord, the radii of the circles are 13 and 15, the distance between the circle's centers is 14, find the common chord.. Answer: A Chord refers to a line segment that is joining any two points of the circle. The endpoints of these line segments lie on the circle's circumference. Diameter refers to the chord that passes through the centre of the circle. In fact, it is also the longest chord possible in a circle. This term is taken from the Latin word Chorda. The 4 basic chord types are: 1. Major Chords. Major chords sound full, resolved and complete. Everything from Tom Petty's Free Fallin' to the Happy Birthday song are built from simple progressions of major chords. Major chords are built by adding the intervals of a major third and perfect fifth above the root
