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
Timestamp: 4:32:01 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

Sir, 3:31:51 iss qu3stion m bina quadratic k v easily compare kr k value nikal skte h 2{cos(pie/2k) +cos(pie/k)} = root3 + 1 {cos(pie/2k) +cos(pie/k)} = root3/2 + 1/2 By comparison cos(pie/2k)= root3/2=pie/6 =》 k=3
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
3:38:52 as this question we can solve only in 30 sec by comparing from the starting equation.....😊 I can think it beacuse nv sir makes us so sharp..... thanks sir for this to makimg my mind sharp.....your sharper mind(me)😅 ✌️ will make you proud one day definitely

Timestamp: 4:32:01
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
Yes
By type 1 also we can solve nah bro ?
y=cos2x +3sinx
y(min) cos = -1, sin = -1
y = -1 -3 = -4
y =1+3= 4
[-4,4]
Wrong

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
