We want this series on daily basis....

[saritashaw]

Your explanation is amazing sir.
We want this type of video on daily basis
Very helpful sir ❤️

sir is ques ko 10s mai bhi kar sakte hai. First ye dekhe ke sinx +ve hona padega kyunki LHS mai mod hai. Isse hum first 2 quadrants mai restrict ho jate hai. Ab dono ki values same honge pi/4 par. Cosx +ve -ve dono ho sakta hai.
To final case is first 2 quadrants mai pi/4 ke multiples. We get 2 solutions for 0 to 2pi. And we have 4 of such divisions in -4pi to 4pi,
total solutions 2 * 4 = 8

I calcuted the steps mentally and it is correct I solved it by second method as it's is easy

[justbadcm]

We can divide the given interval into -4π, -2π then -2π, 0 then 0, 2π then 2π, 4π we can draw the graph for any one interval and then count the intersection points and then multiply by 4 as there are four different intervals this works because sign and cause are repeating function

[harshenginner]

Sir your teaching style is awesome 😎😎😎😎

[honestadministrator]

Herein sin(x) = | cos (x) | being + ve
and -4π <= x < = 4 π
case I : cos ( x) > 0
This implies sin(x) - cos(x) = 0
or ( x - π/4) = 0
Hereby x = π/4 +2 n π

case II : cos ( x) < 0
This implies sin(x) = - cos(x)
or ( x + π/4) = 0
Hereby x = (2 n +1)π - π/4;

This would be the easiest question in this paper in math section if we know the graphical method ❤️

[akshatdon]

Sir you are great please continue one one question in each video as much as possible for you
Thanks you sir

[chandanmaths]

Graph wala badhiya tha sir
Thankyou sir for valuable knowledge

[sankhajitdas]

Sir can we square both the sides and then get the value of sinx=±1/2.. but since LHS is +ve so sinx=1/2 and between -4π to 4π there are 8 values possible

[sandhyachandrapu]

Direct way is way better( not to disrespect sir's video but... You know )

[anshsrivastava]

Sir
NDA math's ke upar ek series laiye.Bas itni daya dikha dijiye.

[mejansk]

Sir app bsc ka maths vi padhao please 🙏🏻.

[Lets_coding.]

sir mod cosx = sinx it means jaha par sinx piositive hogu hme sirf wo hi dekhna hai 0 se 2 pi 2 bar 2pi 4pi 2 bar or 0 se -4pi mei 4 bar total 8 soln

[deepanshu.]

Sir please upload those question solving short video which are solved by any trick or short method less than a min

[mathematicslover]

Apke channel me bohut kush

Sikh ne ko milte hai.
Thank you

[rinijn]

Ye question Hamare mock test mein aaya tha and I did it correct there

[MohitKumar-rzev]

Sir aaj मैने आपसे पहले solution solve kar लिया 😎😎

[ssdignity]

Sir ji as you know we need this sure shot topic videos pls pls make sure type of videos
