00:00 - 00:59 | hello start with the question the question is that if x is equal to a into cos theta + theta sin theta and Y is equal to a into sin 3 theta minus sin theta cos theta prove that 2 X upon DP tatoo is equal to into cos theta minus theta sin theta upon deta 2 is equal to into sin theta + theta cos theta and t2 Y upon DX 2 is equal to seek and cube theta upon A L X and Y on x is equal to a into cos theta + Y equal to a into sin theta minus theta cos theta x and y are both in terms of theta and we have to find |

01:00 - 01:59 | try to you differentiate with respect to Pita before differentiating Idol write the UV method method is that when you are you V dash it will be equal to you dashvi + u b dash and theta cos theta for that will use this formula based upon 3 theta is equal to he will remain outside and inside it will become cos theta will be ka minus sin theta differentiation of cos theta minus sin theta + now first will get differentiate theta and keep sin theta as it is it will be just sin theta because differentiation of theta with respect to Vitamin B1 Plus now we'll keep it is and differentiate this so that will be Pita |

02:00 - 02:59 | and it will become therefore by 3 theta is equal to a into sin theta will become cos theta now cos theta status and will differentiate theta cos theta minus cos theta then we'll keep it as a test and will differentiate cos theta differentiation of cos theta minus sin theta and minus into minus b + theta sin theta in the next step we can write the 4th upon 3 theta is equal to in to get cancelled it will be a theta cos theta and mark 1 and 2 are therefore by Peter is equal to sin 2 theta sin theta and |

03:00 - 03:59 | will be using it later now we will ride will differentiate again because there was D2H by Deepthi theatre to so I write differentiate with Peter once more so different become their 42 X upon T3 tatoo is equal to differentiate this again using the UV method it will be a into cos will keep this as it is and differentiate Pita so it will become cos theta cos theta additives and differentiate cos theta it will be minus theta sin theta and Y to Y upon death eater 2 is equal to a into first milky sin theta status and differentiate the task that will be just sin theta now will keep teeth as it is and differentiate sin theta with L cos theta |

04:00 - 04:59 | this is what we have to prove so well leave it at this and father now we have to find TV to Wi-Fi but dx2 sophos for that will find DY by DX so scandal like this DY by DX is equal to b l upon X by 3 theta is equal to sin theta sin theta upon cos theta sin theta upon cos theta is equal to tan think now you are I will write let DY by DX is equal to z z is equal to tan theta now let's differentiate with respect to theta it'll become therefore |

05:00 - 05:59 | DJ upon 3 theta is equal to secant squared theta differentiation of tan square theta now we got these upon DP now I will write t s e x y z upon x is equal to visit upon teetar Bole by DX upon theta equal to 1 upon 3 theta is secant squared theta upon DX upon d l a m cos theta the reason over from one that this will become equal to know that can be written as secant theta this will be secant squared theta into sin theta will be sikhen |

06:00 - 06:59 | Kyon Peete Upon A L I write the reason since one upon cos theta is equal to visit upon x is equal to this but we said that it is equal to DY by DX to this will become therefore pypy3 x is equal to secant theta upon A L L Y upon 2 is equal to seek and cube theta upon a data base what we have to prove so now we can write the Dekho to X upon 2 is equal to a into cos theta minus |

07:00 - 07:59 | sin theta comma d2y by Peter 2 is equal to a into sin theta + sin theta cos theta and finally to Y upon 2 is equal to secant theta upon a theatre resolve to prove so now we can find the right over here and proof |
