00:00 - 00:59 | is that find the locus of the middle point of the portion of the line x cos alpha + vice and physical speak very easy cost and inserted between the access so we have to find the locus of the middle point of the equation of cos alpha + y Sin Alpha is equal to P where p is a constant and density between the axis superstore due to find X Intercept sofa tight Intercept we have Y is equals to zero is equal to X is equals to cos alpha and for Y Intercept the value of x is equal to zero at Y intercept the Act 2003 get the Y the value of Y is equal to feed your device channel |

01:00 - 01:59 | Supreme heavy can we control the equation of a line ab and bro the equation of line X + B then from corner Texas so let's take this is our co-ordinate desert x x is a white and now this will be this is the equation of a line and left this point will be accepted at this point will be filled by cos alpha zero and this point will be Spa with 0 core Material by sin alpha to find the locus of the middle point so let's take this part the midpoint we can take as comma ki superhit so we can tell that it is equals to zero + cos alpha / 2 Audi can detect that is |

02:00 - 02:59 | equals to X of cos alpha or we can tell that is Sulphur is equal to P B similarly we can co-ordinate ki will be so we can it is equals to zero + t cell for your by 20 + 1 divided by 2 is equal to X of sin alpha aur kya rate that is equals to 2 key equation 1 diesel equation 2 heavier P cos alpha now we can spelling 1 and 2 and add them so we can later that's 1 square + 2 square square and equation of four square and now we can add a + |

03:00 - 03:59 | b square + 2 k whole square Oscar Alpha is equal to 11 is equal to and we can tell that can replace h x and Kate why so we get the lock as a study by 4 x square + b square by 4 y square is equal to one or we can I it is that is 1 by x square or we can enter that is 1 by X + 1 by 4 y square is equal to 1 by it now this is the locus |
