Bhaiyya please solve the following question which came in TS 4
No one in av centre is able to solve
Q45 paper1 aceg
From a point R(5,8) two tangents RP and RQ are drawn to a given circle S=0 whose radius is 5. If circumcentre of the triangle PQR IS (2.3),then the equation of circle s=0 is?
Bhaiyya i know you have limited time but one question wont matter you but it does matter me so please cover up this question. THANKS
its easy , you have to use a graph paper!
Sagar
i hope you won’t mind if i answer ur question
the circumcentre of triangle PQR will be the mid point of R and centre of the circle s
because the quadrilateral formed by PQR and centre of s will be a cyclic quadrilateral
and thus you can find the equation
bhaiya plz take a class on questions of determinants or upload a recording as you told that you will do it in december.In the two classes of matrices there is not any question of determinant discussed by you.

Bhaiya You asked to raise question from TS Paper 1
SET ACEG
Q: 83
In this ques, they have used differentiation to solve the equation
but on integrating there is a difference of a constant, so the LHS = RHS + constant which got removed during differentiation.
Plz check it out.
Bhaiya, it was a really nice class……..
I think this is what most of us expected as it helps in understanding the questions which we couldnt understand from the given solutions….
And those questions which we have already understood ,well, you really make them a lot more simpler 🙂
Wish we had such classes for other subjects as well 🙂
Thanks for your feeback.
bhaiya, i dont know about others.. but i feel that the class was good..but it was conducted very late..so i had already gone through their solutions…so there was no much to learn…
the thrill of the class would have been doubled, or even tripled..if it was conducted earlier..
sorry it was too much cynicism..
Point very well taken. In future, I will try to keep it early.
bhaiya in ts-6 paper 1 class
in ques 72 AECG (where we have to intigrate and find alpha)
it came like ‘cube root of (1-alpha) = 64’
then how can the value be (+- 4) i think it should only be +4
and ans should be only 5! But that is not in options!!
You are right. I did a mistake. But answer is correct. Actually there should be a modulus over the area in left hand side. Due to this modulus, we will get +/- on right hand side. Hence two answers.
bhaiya Plz discuss ques –
TS-6 Paper 2 ACEG
Q- 41,44,45,46,49,,51,54,59
bhaiya, i attended the session but missed a few questions coz of internet problem. it wud be great if u upload video of this class. thanks
Please upload TS 6 paper 1 video. Missed it due to preboards. Thank you.
Bhaiya.. I think u must not make these videos of TS 6 Qs discussion as public….
Instead, u can provide us with video links on Edmodo!!
They are not public.

bhaiya in the ques no. 43 ts 6 paper 2
the value of k>0 so how it can satisfy K= R-{0,1}
You have a point. It should be only positive values excluding 1.
Bhaiya what I meant by this was that on differentiating we got b=4a.
Now we replace b=4a in the integral, we get LHS = RHS + 1/4.
So, solving by taking derivatives and equating gives a wrong ans.
Plz reply…..
And bhaiya plz don’t stop taking these classes as they’re very useful…..
bhaiya please upload the recording of week 52
