1:07:41 tan are bounded and cot is unbounded tan value going the zero and cot going ♾️

[@MahipalSingh-p6m]

8:20 b is correct answer

[@Tainkio]

52:11 1-cos2@/sin2@ = tan@ Prove karane ke liye phele ham 1 ko sin²x+cos²x convert karenge or cos 2@= cos²@-sin²@ ke property laga denge ..or sin2@ ko khol denge 2sin@cos@ =Sin²@+ cos ²@ - (Cos²@-sin²@)/2sin@cos@ = 2sin²@/2sin@cos@ = Tan@ hence proved ❤❤

[@chetanprajapati0212]

33:35 ..1st ans = -cos thita , 2nd ans = -tan thita , 3rd ans = - cosec thita

[@manavdudharejia]

Best explanation on KZbin by GOAT OF math from 2.0

[@rishabhjain1737]

Real goat of jee mathematics ❤❤🎉🎉

[@rishabhjain1737]

1:07:43 infinity and,- infinity

[@GovindBhardwaj-babu]

Vote for manzil series 👍👍❤️

[@nehasah9290]

1:07:44 both tan and cot are unbounded since its value goes to infinity on pie^- /2 and - infinity on pie/ 2 + ( for tan )

[@Anuragsaroya]

Adv happy birthday to ashish sir 8th oct❤

[@Tainkio]

52:12 1+cos2@/sin2@ = cot@ Prove karane ke liye phele ham 1 ko sin²x+cos²x convert karenge or cos 2@= cos²@-sin²@ ke property laga denge ..or sin2@ ko khol denge 2sin@cos@ =Sin²@+ cos ²@ + (Cos²@-sin²@)/2sin@cos@ = 2cos²@@/2sin@cos@ = Cot@ hence proved ❤❤

[@mohitpanchal1026]

33:30 a) -cos@ b) -tan@ c) -cosec@ where @ denotes angle

[@SHORTEXPRESS-]

Koi short trick hai kya bhai

[@alonetime..3911]

Ashish sir supremacy 🥹🥹🥹❤❤... Great Explanation ❤️

[@AlokChoudhary-v7h]

33:36 a -costheta b tantheta c -costheta

[@AstitvaSingh-dq9vy]

2nd mein -tantheta hoga

[@hariomkumar3449]

Wah sir aap really me maths ke God ho ❤❤ sir me aapke Charan sparse kr rha hu asirwad de dijiye ❤

[@ShrutiBehl478]

09:24 i think b correct hai Cot infinity to 1 jata hai toh cot ki power cot max hona chahiye..isi se hi mera question solve ho gya under 30 sec. Easy..

[@Noname-l4i4t]

How explain it ​@@Tech_jena

[@Tech_jena]

@@Noname-l4i4t a correct Bhai

[@supriyaallampati9198]

yes. b correct

[@adityakulkarni7968]

Yes Bro, same here, B is correct....

[@MahipalSingh-p6m]

Under 10 sec me solve Kiya without pen notebook

[@Tainkio]

33:36 1. costhetha 2. - tanthetha 3. -cosecthetha❤

[@Dip0326]

9:24 option B

[@mohitpanchal1026]

1:04:52 Cos ki value 1 at even π and sin ki value -1 at (4n-1)π/2

[@manmeetkaur02]

9:23 b is correct

[@rishabhjain1737]

1:09:34 both - infinity

[@tarolattew]

1:39:50 8 is ans

[@Tainkio]

9:17 ANSWER IS B

[@YashKolwal]

52:11 sir ji proof👇🏻 we know 1-cos20=2sin²0 -> sin20=2sin0cos0 Then 1-cos20/sin20=2sin²0/2sin0cos0 (cancel 2sin0) 1-cos20/sin20=sin0/cos0=tan0 Hence Piroved❤👑

[@nehasah9290]

9:21 b option

[@ArihantKadam]

9:06 B correct

[@nehasah9290]

28:43 - ve , -ve +ve

[@Dev-s7b]

No,all 3 are negative..

ASHISH SIR TEACHER CLASSIC (ASTC RULE)❤

[@Tainkio]

27:59 cos + lie in 3rd quadrant Tan - lie in 2nd quadrant pie is 403.8π Sin + lie in 2nd quadrant 405.2π

[@satyaprakashsingh2422]

Tan and sin lie in 4 th quadrants

[@AlokChoudhary-v7h]

1:05:15 cos 0 pe 1 aata hai

[@DikshaNegi-v3d]

52:30 (1-cos2A)/sin2A =2sin²A/2sinAcosA =sinA/cosA=tanA (1+cos2A)/sin2A = 2cos²A/2sinAcosA= cosA/sinA=cotA

[@lucky00.7]

No,we can't take any x=sinth or costh because the range of sinth or costh belongs to only (-1,1)

[@lucky00.7]

37:57

[@bhrigupandeyxbroll0357]

tah 3 :- @ans:- 9Π

[@YashKolwal]

33:33 GURU JI Sin(2023π/2 - 0)= cos 0 Tan(2024π - 0)= tan 0 Sec(2025π/2 + 0)= - sin 0

[@manavdudharejia]

-cos -tan +sin

[@rishabhjain1737]

9:25 B is correct answer ❤

[@Tainkio]

1:09:34 cosec going to infinity+ and sec going infinite + both are not bounded

[@tarolattew]

8:29 b

[@Tainkio]

37:01 not assume bcoz sin range is -1,1 cos range also

[@avishkar6446]

9:00 ans B option

[@DelightfulAurora-gc4md]

Cos(2 theta) is the most widely and wildly used formula 51:03

[@Soni12312]

33:32 -costheta -tantheta -cosectheta

[@kishormaske9247]

7:30 i think ye bohot complicated hai hamare tution me isse easy batataya Gaya hai

[@SKCphysics]

Attendance Lakshy 2025 👍👍👍

[@mohitpanchal1026]

37:45 Har x ko sin ,cos theta assume ni kr skte kyuki uski range (aukaat) ya possible values hi [-1,1] hoti h

[@RaushanKumar-o9w]

Attendance for jee advance preparation
