Last ans is (cosec@-cot@) . Use this Cosec@-cot@=1/(cosec@+cot@) and then solve :)
Hnn bro 10 ko ncert ka qsn h
Last ans is tan(A/2) ...(lets replace theta with A)...
Solution :
(1+cosecA -cotA)/(1+cosecA +cotA) = (1+ cosecA -cotA)/(1+(1/(cosecA-cotA))) .......(since (cosecA-cotA) (cosec A +cotA ) = 1)
On solving , it becomes : (1-cosA)/sinA .
Now : (1-(1-sin^2 (A/2)))/2sin (A/2)cos(A/2) : on cancelling sin term, the answer is Tan A/2.....hope it helps
Thanx..
thanks but divided by 2 is missing
Bhaiya Aisa nahi tha ..
(1-cosecA-cotA)/(1+cosecA+cotA)
Ye solve Karo
Ab trigonometry me ku66 v bhari ni lgg rha hai Guru jee ....sbb easy lgne lga aapke ess Hard mehnatt k karan ....Thnxx u so much sir...
Good
Kaun kaun bhai sir ko great mante hai

Bhai manta nhi sir vaise he great h
Jo sir ko janta wo sab
Q. 6 tan^2 (π-θ)= - tan^2 (θ)
Finally answer is tan θ
Where θ = a
wo sir ne shayad use 180+a/2 assume kar lia jaldi me
@@keyanroy47 ha ji. Sahi kaha tumne ☺️
Its because there is tan^2
Negative become positive in case of sq
@@shivangipurohit5003 right
Are bhai Square me possitive ho jata hai
For those who are not getting last qn..put cosec@ - cot@ as 1/ cosec@ + cot@

@@devendrasaini5728 bhai tera galat hai

You are the best faculty of mathematics Sir aapka Saat hum sab students ki dua h Sir aap esa hi aga badta jao
Sir plz make your aap from which we get online class from jaipur. You are teaching from last 6-7 month only 3 chapter is completed. We salute ur efforts. But we want to complete syallbus before ssc exam .so start new online batch. Thanku very much .sir you change the scenario of teaching of competitive exam
Online class chal to rhi bhai unacademy pr
Que 6 me tan ki value 2 quarter me - ki aygi na. Plz solve
Yes, wo by mistake ho gya h. So tanA should be answer
Nhi bhai vo shi h ans isliye shi h kyu ki negative ka square + hota h isliye -tan^2 ka +tan^2 hoga
Sir 6th question, denominator m
1-tan^2a/2 n hoga kya... Bcoz 2nd quadrant m tan -ve hoga.. to ultimately formula tan2a ka n bn jaaega.. and answer will become tan.a...
Plz check nd reply sir....
Bilkul sahi bhai. Main bhi yahi notice kar rha tha.
Bulkul sahi
Tan A
Jai hind.. Yes bro
It is not the case bro. In the denominator, it is plus tan^2 A and not minus as we think. Because the given expression is in square. In tan A, it is negative but while you are squaring the expression will be positive. That is 1 plus tan^A in the denominator. So obviously SIN A will be the correct answer..
Sir second last question m tan(p-a/2)= -tan a/2 hoga
dev paliwal han bhai
Isme tan square m so change ni hoga
Great work sir
Unpayable work u r doing
Sir last ka answer...... Cosecthita-cotthita hoga....
Isme bs 1 ke jagah cosecsquarethita - cotsquarethita rkhne bhr ki deree hai....
sir question no. 6 mein tan(180-a/2) = -tan a/2 hoga na. answer should be tan a. please comment
Bhai tan square(180-a/2) h isliye 2 baar - aayega aur wo + me change ho jayega
Question number 6 ka ans tanA hoga
tan(180-A) = -tanA
Tan(90-@)=-tan@ होता हैं
पर tan^2(90-@)= tan@
होगा सर ने बताया तो था square में नही होता neg.
thanx dinesh
Sir Q.No 6.... tan(π-x)= - tanx should be used
Sahi bola bhai
Tan©\2 hona chahiye.sir
Thank you very much sir for these useful series 🙏🙏
Sir 6th question me tan negative me nhi hoga kya tan(180-a) = -tan a
Tan ka square diya hua h toi positive hoga
Thanks sir for your basic concept instead of putting theta you expalined every question throughly
Q.6 me tan^2(π-a/2)= -tan^2(a/2) hoga sir
So that answer will be tan(a)
Ans. of 7th
=Cosec(x)-Cot(x)
{Hint:- put 1=cosec²x-cot²x}
Kaise aaya
6 no wala questions 1 - tan^2a/2 a rah hai
tan (2π-a)=-tan(a) but yha tan ka square h isliye tan positive ho jayega
Sir plz ek aapse aur request h ki video ki length 45 minutes se 1 hour ke beech ka kr dijiye Aur trigo ke baad algebra start kr dijiyega jiise hmara poora advanced maths complete ho jayega thnku very much sir for ur cooperation....
