00:00 - 00:59 | find the position vector in R provide the line joining a in the first part of the internal second part 2 in externally write a letter start and Foster cal let me explain the question you in the diagram of the first time that the line segment ab to fit in that point are that is dividing internally the join a b in the ratio 2 ratio 1 using Section formula to calculate the coordinates of art that if X Y and Z so let's find out I can apply the formula Section formula hair that will be the x-coordinate will be |

01:00 - 01:59 | close to 2 into 3 plus into minus 1 divided by X + Y is equal to 2 + 2 + 1 into 32 + 3 + 2 root 6 minus 4 x corner 24 hour cotton Canvas 13311 upon 3 letter format will be - 4 + 3 - 13 of a when R is avoiding the AV internal check out the wedding let's have a second part that is when the car is dividing the joint of Ab internally and externally |

02:00 - 02:59 | we are given the points A that is -23 and point that is 35 to that point are is dividing the joint of A and B in the ratio status 2018 to have to apply Section formula to solve this question let's let's supply Section formula hair applying the Section formula to find the coordinates of the Earth is X that will be equal to 2 into 3 minus 1 into minus 2 minus y equal to 2 into 5 25 - 25 - 1 into 1 minus cot theta |

03:00 - 03:59 | equals to minus 2 2 into minus 2 + 1 into 3 / 6 plus two that is equals to 8 it is 8-10 minus 1 equals to 9.1 - 2 + 3 that is equals to mines of Core and 35 - 4 - 7 so the coordinates of dividing the joint of a b in the ratio 2 ratio 1 that is |
