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.
Cut a 1-foot section of serving thread from a spool. Wrap the thread around the bow string 2 inches below the damage. Tie a single overhand knot in the thread. Pull each end of the thread to the opposite side of the knot and tie another overhand knot. Continue alternating the knots until you are 2 inches above the damaged section. Tie a double overhand knot on the final wrap to secure the serving repair. Cut the ends of the serving thread, leaving a small tag on each.
