Radians are a unit of measurement for angles. They are the standard mathematical way to measure angles in trigonometry and calculus. Unlike degrees, which divide a circle into 360 parts, radians measure angles based on the radius of a circle.
One radian is defined as the angle subtended when you take the radius of a circle and wrap it around the circumference. In other words, if you were to walk along the edge of a circle for a distance equal to the radius, you would have traversed an angle of one radian.
In most mathematical calculations involving angles, radians are preferred over degrees because they simplify many formulas and make mathematical relationships more elegant. For example, the trigonometric functions (sine, cosine, tangent, etc.) are often expressed in terms of radians in mathematical contexts.

This is really great sir! Thank you! Can't wait for your class 12 course soon!!!
You're very welcome!
Omg 😱, I just wished for this video like a week ago. Thank you sir ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Most welcome 😊
We need more teachers like you sir… my son had been learning a lot through your videos.. thanks a lot
Sir please make a video on basic statistics 📊 😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
r1 : r2 = 5:4
Thank you sir you are a fantastic teacher❤😊😊
Welcome
Amazing Maths video!!!
r(1) : r(2) = 5 : 4
Sir is the answer for the home work q is 15:12
I am Very new this channel Although i had watched your videos 1 years before.
The Video was super informative and Amazing.
Thank you sir for making our concepts crystal clear ❤😊 Your videos helped me alot ! Informative & practically I understand much better from Monacha Academy ❤
sir you have made error in calculation 4x90x7= 2520 not 2250 but any way it is ok
sir ...really you are energetic ❤
The ratio of the radii of the circles in the H.W. question is 5:4 👍🏻
Same
Yes
How did you calculate it since the arc length wasn't given?
@@user-mp7wn8tr5g The arc length gets cancelled out while we solve for the ratio 👍🏻
Hey Monacha do you also teach biology...I have an upcoming exam and I need help on some topics
Sir thank you for this video i have a test coming up and im sure im goonna ace it now
OK, your video is very good, but you have not explained why using Radians is better than using degrees. The 360 degree circle is arbitrary. I want to use a 378 degree circle so I can divide 7 into in 54 for my accurate Sacred Geometry drawings on CAD. How do I do this and how do i find the points on the circumference for my rays? Thank you.
I don't believe my eyes finally seeing you explaining radians sir. Now I am sure I will be perfect with them.
Super class sir , thank you very much
We are not converting the fractions into mix fraction, we are converting them into improper fraction, hope it helps the students
Hello sir I😄😄😄 like your ways of learn and thank you for your helps
Thank you so much sir ,,, I'm glad to study with you sir ❤ ,,,, you teach every hard concept in an easy way 💖 I need a teacher like this especially in physics and mathematics ❤ thank you very much sir love from Hyderabad ❤❤❤
5:4
Thank you sir❣️
Sir please make a small video on making algorithm and flowchart to add the first 100 natural numbers and
5:4. Sir ji
(4*90*7)=2520 not 2250
Yes!
Sir please make a video on preparation of 2024 board exams
R1:r2 = 5:4
very nice
Sir please make one video on calculus.
Please conduct live sir
When it uploaded
thanks you so much sir you are teaching very nice 👍 please may you make a video about equation of circle in additional math and calculus, even differentiation.
🙏🏻🙏🏻
H.W ans.17/12
sir teach chircles and area related to circles class 10 cbse please !!
12:18 , it will be 1.746
Please in the homework assignment you gave how will I know the value of l in the formula
the homework question which you have shown in the video
it is in the ratio 4:5
r2:r1 = 4:5
*Your Speciality of making concepts Super Easy made me fall in love wid this Channel* 😊❤
What is minute in angle
🥰🥰🥰
Sir can you plese tell quardiletrals for class 8❤
Hello sir🎉
❤
Will u help me to do trigonometry identitic problems easy and crystal clear sir plzzzzz😢😢😢😢😢
Angle should be used. Not theta, x, or whatever. Math and physics book are so bad, so not straightforward, inefficient.
75/60=(r1/r2)(l2/l1).
l2=r2,l1=r1, right side will be 1
So not getting answer
4 I:5
4:5
I like this video at 2 min😮
❤❤❤❤❤
The ratio of their radii are 5:4 ....
Plsss tell me the answer sir
Please how did you calculate it since the arc length wasn't given?
It is same length @@user-mp7wn8tr5g
So we can calculate the value of both the arc lengths and equal it with the answers to find the ratio
If you don't understand what I'm saying feel free to ask
At first I did several ways to calculate the answer and ended up completely blank
Yummy cake by the way 😂❤😂❤😂❤
Hello sir
Thanks for the video🙂! looks like i came early😂
Awesome video at least its beneficial to non native Hindi speakers else I wouldn't have watched the video. Please do not make it in Hindi. Thanks
How this formula formed
First comment and first like
Thanks for watching 👍
I use Jain 108 Pi, which is 3.144. He has proven this is the real Pi.
Hi sir
Iam Gayathri r. Ssc class 10th st. Marks high school
4/5
Pls reply
Systumm!!!!!!!!!!!!!!!!!
Thanks
Ok
⁵
Sir plz reply 🙏🏿🤲
r2 is 4,r1 is 5
Nhi bhai..4:5 ratio hai value nhi .. so tum keh skte ho r1 = 4x aur r2 = 5x
Sir bas na 😂😂😂😂
is it wrong
You are mad ra
Sir khana khao bhuk lagi hai teko 😂😂😂😂😂😂😂😂
I think its physics
Yes it is physics of class 11😊
Pls speak Hindi in any video
😂
5:4
