00:00 - 00:59 | in this question we have to differentiate this universe and this is sign of x divided by 1 + cos x with respect to the Exo from where we can solve this question as we have this tan inverse and this is we have sin x divided by 1 + cos of acts as we know that formula for this this is we have the formula of Sin of 2x Sin of 2x we have the cells to sign of X and discourse of access so from where we can simplify the sign of X this will be the this is we had to sign of X by 2 and this course of X by 2 here and we have another formulas 1 + cos of 2x this will be equal to 2 cos sin cos square or fax from where we can write this to cos square of X by 2 so from where we can write the said this is one formula and this is s formula so we can apply this so this will become tan inverse |

01:00 - 01:59 | we have to sign of X by 2 hair and the season 2 course of X by 2 hair and this is / we have this is too scared of X by 2 hair now this will be cancel out by this analysis we have to will be cancelled from there now we have the remaining term is this is we have 10 inverse and this will be sign / ko so this will become 10 of X by 2 hair so this this will be the now we have this this will be equal to we have this time was this will be X by 2 year so this is the function of this is a perfect now we have to differentiate this this weekend I advice we have to find the DY by DX so we can write this this will become one by two years of this is our answer thank you |
