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.
At this point, you need to make an initial twist in the cable, in such a way that the cable resembles a perfect lasso. Be sure to pull the cable with care because if you stretch it too much, you might end up damaging the wires inside the cable. 1  Start wrapping the cable with a natural flow. 2  As you proceed, you will eventually start feeling your way through the process. 3  Make sure that no kinks develop in the wire while you wrap it.
