Conics: Parabolas: Introduction (page 1 of 4) Sections: Introduction, Finding information from the equation, Finding the equation from information, Word problems & Calculators. In algebra, dealing with parabolas usually means graphing quadratics or finding the max/min points (that is, the vertices) of parabolas for quadratic word problems. In the context of conics, however, there are some additional considerations. To form a parabola according to ancient Greek definitions, you would start with a line and a point off to one side. The line is called the directrix; the point is called the focus.
However, wrapping the kink free cable is much easier than a kinked cable, which means you will be saving some time in the long run. 1  Hold the connector of the microphone cable firmly in the left hand and slowly pull the other end towards yourself with the right hand.
Let's get to it: 1  Tie a short loop in the end of your string material and clamp it temporarily to one of the pegs. 2  Put 20 wraps (40 strands total) around the pegs, taut but not tight. 3  Serve 5 of half of the strands in the exact center of the two pegs, as shown in the figure below. I have a couple of lines on my board just to show me where. I use a couple of pieces of scrap wood to spread the strings here. This allows me enough clearance to use my serving jig. I use the diamondbraid for this part.
