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.
A triad is a chord constructed with 3 notes. When in root position (the root note is on the bottom) each note is a third away from the last (if intervals are new to you check out the intervals tutorial). Triads are a basic chord structure and the basis of how other types of chords are constructed. There are four types of triads: 1  Major. 2  Minor. 3  Augmented. 4  Diminished.
