    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

    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

    1:21:39 sir agar jyda bada angle ho to 360° se divide karna easy hota hai kyuki tab hume direct pata hota hai ki 360° ka multiple aayega yani 2pi lakin 450° kitna hoga aapko to direct pata chal gya lakin mere ko thoda sochne ke baad pata chalta hai
    1:22:29 aapka cos30° aaya or mera sin60° koi difference thodi hai dono mai value to same hi hai
