SpletSo that takes care of the "order" of the chords, but what about the "length" of each chord? I would suggest starting with one chord per bar, which means all the above phrases are 4 bar phrases. Then just repeat each phrase 4 times (for a total of 16 bars). Depending on your tempo, if the harmonic movement feels to slow or too fast, just half or ... SpletSolution: Focus of y2 = 4(x− 1) is (2,0) which satisfies the equation y = 3x− 2 3. Hence, line y = 3x− 2 3 is a focal chord. Now, the length of the focal chord equals to 4a cosec2θ where a = 1 and tanθ = 3(orθ = 60o) ⇒ length of chord = 4×(cosec2(60)o) = 4× 34 = 316 units Splet26. sep. 2012 · Find the length of a chord of a circle.
