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.
How to Use Armored (BX) Electrical Cable. Electrical cable encased in metal sheathing is often used in basements and other areas where the wire is not encased in a finished wall.It is handled differently that standard Romex (non-sheathed) cable.Ad.ut across the armor-not with the spiral. It is not necessary to cut completely through the armor. When the cut is nearly through, grab the wire above and below the cut and twist sharply-this should break the remaining armor without the need for the saw to contact the wires inside. Use caution-the metal edges are sharp.
