In reality, however, the long-term mental health state of many cardiac arrest survivors is not typically considered or assessed, the researchers write in their report, which appears in the journal Resuscitation.
What is the difference between Chord, Tangent and Secant? â¢ A chord is a line segment and both secant and tangents are straight lines. â¢ Chord is a line segment with the end points lying on a curve while a secant is a line passing through exact two points on a curve. â¢ A tangent is a line that just touches and passes through a point on a curve. It is a special case of secant where the two points on the curve overlap.
1 A chord is a combination of three or more notes. 2  Chords are built off of a single note, called the root. 3  In this lesson, we will discuss triads. They are created with a root, third, and fifth.  A major triad (or major chord) is built with a major third and a perfect fifth from the 1  root. Let's write a C major triad.
