00:00 - 00:59 | given that considered the function f x is equal to root 1 + cos x + root 1 minus cos x by root 1 + cos x minus root 1 minus cos x then question H block 2225 then effects in 2 + xy2 10584 + 2 Cos pi by 4 minus 2 10584 -2 now takes effect is equal to this is root 1 + root 1 minus cos x y root 1 + cos x minus root 1 minus cos x is the formula to access is equal to 2 cos square x - 1 |

01:00 - 01:59 | aur 1 minus sin square X formula used to cancel out the one in this question we will use the formula 2 cos square x by 2 minus one in this section we will use the Formula 1 minus minus plus 4 final square to be used 1 + cos square x by 2 minus 1 minus 1 minus 1 + 2 sin square x y 21 and when cancel out it takes you to common common |

02:00 - 02:59 | esmod was actually to sign it takes root 2 sin x by 2 root 2 cos x by 2 minus sin x by 2 that cloth to add route to cancel out this will be equal to cos to sin x by 2 cos x by 2 minus sin x by 2 now we have given that X belongs to 225.225 225 |

03:00 - 03:59 | we will take X / to this is pi by 2 then later than 52 belongs 222 S Garden in second quadrant we know that cos x by 2 is negative this is cos x y to find its way to is positive widal test positive minus cos x by 2 minus sin x by x minus sin cos x by 2 cos x by 2 minus 3 x 2 |

04:00 - 04:59 | - will take so this is cos x by 2 minus sin minus minus plus sin x y - cancel out divide divide in numerator cos x y to divide in numerator and denominator Y cos x y to this will be equal to 1 minus 10 x y to this is oneplus this is 10 x y to take this is one is 10 value of tan pi by 4 minus 10 x to Y 1 + 1 into 10 Activator |

05:00 - 05:59 | this is 10584 into 10 x y to this is the value of tan pi by 4 minus x y to this is our answer option is correct 4 - 210 5 by 4 minus 2 |
