00:00 - 00:59 | vertex and focus of parabola are -11 and 3 respectively then find the equation of directors so you can see that I had already made a rough diagram for better understanding of this course B so according to person here we have a vertex which is -1 Kumawat right so this is Vertex let's say it 7 co-ordinate -1 coma b and b having focus is to cover thyroid so let's say we this focus of parabola its it is 23 so this is Axis of parabola this one is directors practice so you can see |

01:00 - 01:59 | that directors is perpendicular to the axis of parabola the festival will grow first phone they will calculate the slope of axis of parabola axis of parabola slope is equal to y 2 - 51 which is 3 minus 1 divided by X 2 - 1 which is 2 - 3 - and becomes plus it's come South to White thing right so let's see slope of x axis of parabola M1 right and flop director szanto directors and access parallel or perpendicular to each other its mean product of their slow -18 slowed slope |

02:00 - 02:59 | of directors is comes out minus 3 by 2 or more that the vertex is divide what is the midpoint of the photo directors and focus light LED se point C its mains is midpoint midpoint midpoints of P and write its SI unit of sea as I write so -11 is equal to hear X + 2 Y + 3 / to solve |

03:00 - 03:59 | this then you will get -1 if you solve this then you will get with this then you will get this done this is equal to X + 2 divided by 2 or 1 is equal to Y + 3 / to write you get minus 2 is equal to X + to write any 2 get 2 is equal to Y + 3 is equal to Y + 3 by |

04:00 - 04:59 | its implies that implies x is equal to minus 4 right and Y is equal to -1 show the equation of directors we can write the equation directed by using the 1.4 because here we having a point and slope of direct 21.4 is Y minus 1 is equal to M bracket x minus x 18 rear yy1 is -1 so it's become + 1 is equal to M minus 3 by 2 minus 3 by 2 x minus x 1 which is here -4 its its Sugam if you solve this then you |

05:00 - 05:59 | will get + 2 is equal to minus 3 x minus 12 right and also as 3 X + 2 y n + 14 is equal to write so this is our equation of directors in this person thank you |
