I literally smiled after this video. I was having so much trouble with this topic. Excellent explanations sir, look forward to learning from your other videos
Thank you very much sir, am in hostel but i tried to get chance to watch your video and its interesting i wish you're the one who teach us ❤❤❤❤❤😊😊😊😊😊😊 📒 noted
Whenever the angle is used not as part of a trigonometric ratio (sin), then you must use radians. When there is sin, you must use the angle according to your calculator mode - which is usually degrees by default.
This will depend on the calculator mode. It is usually in degrees unless you set it to radians. If it is in degree mode, you must use angles in degrees whenever there is a trigonometric ratio involved.
Hi Krishwini. Differentiation is a huge topic. It will be a bit long to make one video on the whole topic, but I'll definitely do one for revision later. For now I have covered two subtopics: Differentiation by formula - ua-cam.com/video/x1qxaTVeUrc/v-deo.html Max/min values - ua-cam.com/video/5UlsgBrPO6w/v-deo.html
It was a great class, but can you pls invade of next time show your working, I still don’t get the same answer. Attests with the workings we will know where our mistakes came from. Thank you.❤
That depends on what unit of angle you use for your trigonometric ratios. If you use radians for an angle x in sin x, then the calculator mode has to be in radians. If you use degrees for x in sin x, then the calculator mode should be in degrees.
Hi Zaleha. You did not do anything wrong. It is just different values of pie. You used the full value of the constant for your answer. I used 3.142. Unless the question specifies which to use, you can use either. Sometimes the question will ask you to use 22/7.
@@MrRuelTuition I really do love this video,I have a small suggession if u are open for 'em😇.Could u pls do a full vid on differentiation and integration , and straight line graphs for cambridge add maths students as your next video😇🙏🏻
This depends on what the question is asking. You apply the same principles for the circle part and then, use the fact that the angle between the tangent to the circle at the point and the radius at the point is 90°. You should be able to work it out from there.
Thank you so much! This is so useful and very easy to understand!
Thank you for taking the time to comment. I'm very glad it is helpful! 😊
@@MrRuelTuition keep it up!!!

Can you do classified questions for circular measure(past papers)
thank you so much this was so useful!! you're an amazing teacher!
Thank you for the kind comments. I'm really glad it was useful! 😀
A masterly presentation.
Very useful. I understand all that you teach😄
Thank you for your excellent explanation👌

so far the BEST video on this topic! thank you so much! it helped me al ot
Thank you for the really kind words! I'm always happy when my videos are helpful 😊
Afternoon sir!😄 On 12:43 i didn't get the same answer when I put in my calculator. Iam getting my answer in decimals plz help me. My answer is 23.03
this was an amazing explanation
This has really helped me am ready to write my exams
That's great. All the best!
Such a good video ill share this with my friends
Thank you. I'm glad to hear that, please do! 😊
Thank you sir, you saved my exam 🙏
I'm very glad 😊. You're most welcome.
Thank you ... I have heard
Good lesson 👍🏻
Thank you, I hope it helped!
sir my question is can't we just convert the angle to degrees if it is given in radians at the beginning and use the theta/360 formula?
Really helpfull🥺!! thankyou so muchhhhh
You're most welcome. Really glad it helped ☺️
Sir should I use the calculator in degrees or radians when calculating length of segment
Whenever the angle is used not as part of a trigonometric ratio (sin), then you must use radians. When there is sin, you must use the angle according to your calculator mode - which is usually degrees by default.
It was a great video truly , keep it up
Thank you very much! 😊
very helpful my guy, thanks so much
Wonderful! You're most welcome 😊
AMAZING VIDEO.
Thank you 😊
bless you sir

This is great
Thanks this is great

great video
Thank you!
Thanks a lot sir. It really helped me.

Is it ok if I use radians where you used degrees
This will depend on the calculator mode. It is usually in degrees unless you set it to radians. If it is in degree mode, you must use angles in degrees whenever there is a trigonometric ratio involved.
thank you so much sir, sir please do video on chapter 2 {full chapter with examples}

very useful
very helpfull thankyou

I am watching it now
great video, what app did you use for this?
Thank you 😊. I use Microsoft OneNote as the "blackboard".
Nice
Thank you!
thank u sir helped a lot
You're most welcome. I'm glad to hear that! 😊
Don't you have some questions papers
Did we need to change mod to radian in calculator in these topics
That depends on what unit of angle you use for your trigonometric ratios. If you use radians for an angle x in sin x, then the calculator mode has to be in radians. If you use degrees for x in sin x, then the calculator mode should be in degrees.
@@MrRuelTuition OK Thx 😄
hello sir,can i know on 27:16 why i get the answer 0.42478 ? what did i do wrong?

Is this for IGCSE?
sir for example 2
4(330*pi/180)
=23.03
im getting this. is it right or wrong ?
Yes it’s right

How to solve a question that includes tangent ?
This depends on what the question is asking. You apply the same principles for the circle part and then, use the fact that the angle between the tangent to the circle at the point and the radius at the point is 90°. You should be able to work it out from there.
mantap
Sir i solve them with your formulas but i did not end up getting the same answers?
Hmm..maybe check your calculator mode? It should be in degrees
Sir, when calculating the area of a segment, the answer when using degrees is not equal to when using radian.
When using the formulas without sin, then the substitution must be in radians. You will not get the correct answer in degrees. It will be different.
Okay thanks sir
Understood
