[destroyer]

are u kidding me this is literally plus level content not to compare both are my fav teachers i followed manoj sir in trigonometry and he made it strong for me but today i saw his entire lecture and he made it even stronger save him unacademy he is literally a gem for maths love u sir

[AkashAkash-linj]

Not praising, but these vora pair is just something else, how can they teach in such a beautiful manner so that each and every student from initial stages can compete adv level sums, take a bow both, many hearts from Andhra nishanth sir❤❤

[edunitian]

Sir aap itna accha explain karte ho ki Mai sara pyq Question khud sa solve karna ka kabil ban jata ho NV sir is best

[BLG]

for 3:14:23 question best short way is to convert cos 3pi/8 to sin pi/8 and take sinpi/8 and cos pi/88 common and simplfy, you can do it in 4 steps.

Nv sir has 100 years of exp of teaching i am following him from unacademy jee then atoms and my math is improved thanks nv sir

[abhirajsinha]

3:32:54 I directly took 2 common, cos theta + cos 2 theta= root(3)/2 + 1/2, which is cos 60 and cos 30 values. Not exactly foolproof method, but faster

[m_ishaa]

Jo maine paid batch se nehi samajh parahi thi ooh apne 15 mins mein samjha diya... Thank you sir 🎉

[syedsabahuddin]

Easy way to skip the tough calculation at 3:33:00
From 2 cos pi/k+ 2 cos pi/2k= root 3+1
Take 2 common and send it to the other side's denominator
Cos pi/k+ cos pi/2k= root3/2 +1/2
Cos pi/k + cos pi/2k= cos pi/6 + cos pi/3
Comparing, pi/k= pi/3
Hence k=3

[itsvarsha]

Ur the best teacher for both jee mains nd advanced

...🥰

[sparshbhutada]

3:32:41 take 2 on the other side and they will form angles π/6 and π/3 which will equal to π/2k and π/k making k = 3 easy solution!

[sohampramanik]

HATS OF TO YOU SIR FOR YOUR DEDICATION.

[asiandramaland]

Humara math teacher kaisa ho.. Nishant Vora jaisa ho🤟🤟🤟🤟...Sir, You make me fall in love with Mathematics .God bless you sir..

In max to min part type 3 there is a mistake in the question y= cos2x+3sinx=1-2sin²x+3sinx
Correct answer is range is [-4, 4]. You can use linear inequalities
-1≤sinx≤1. Therefore, -3≤ 3sinx ≤3.
0≤sin²x≤1. So, -2≤ -2sin²x ≤0
Adding both inequalities, -5≤ 3sinx-2sin²x ≤3
Adding 1 on all sides. -4≤ 1+3sinx-2sin²x ≤4
