I'm a student in Turkey who is in grade 11 now and i think that it's safe to say that i finall got the idea of identities. It sounds more complicated in turkish but you taught me in a way that my own teachers didn't. I have my exam tomorrow and just wanted to let you know that you are incredible!!!
When we don’t understand, my teacher shows us these videos... so basically you were my teacher for the term ... and I’m just excited to let you know that you make maths so possible to pass🥺
My only regret is I wish I found this channel sooner😔. But now I'll make sure my whole maths class finds you. Thanks a lot Kevin you don't know how many marks you've increased in all our lives. ❤❤❤
Thank youuuu sir Kevinn!! You're saving lives😭😭my teacher did a worked example and got a different answer from the book then he said the book was incorrect but I wasn't convinced cause the way my sir found that answer was kinda suspicious to me and wasn't making sense so I told myself when I get home I'll just watch sir kevin then do it again until I found the book answer and then just a few mins into the vid, I stopped to do my example and I was able to to find the exam answer as the book in less than 3 mins! Thank you so much, you opened my brain on this topic
On number 4 Kevin you can start at 1 as sin Squared theta +cos squared theta and the you solve its from there is minus of the sin squared theta and would become cos squared then minus sin squared theta divided by the denominator of sin theta X cos theta it much easier that way
Oh I see what you mean :) Yes because then it becomes cos^2 - sin^2 / sincos And then you split it up to become cos/sin - sin/cos which is then cos/sin - tan. Nice!! :)
I really thank you sir you video was of great help to me cuz l was not understanding anything in this topic .thank you once more .just hope you will continue to help those in need of you 🎉🎉
Please explain the concept of fractions like what are the conditions when you should cross multiply and when you should do direct multiplication cause i thought whenever you see two fractions whether you add or subtract or divide or multiply you just cross multiply
Hello! Not sure when I will be uploading to RUclips but you can checkout my course. Try it for free for 7 days. It has trig graphs :) www.kevinmathandscience.com/7dayW
When there's a division sign and we want to multiply, when do we use the flip over cross multiplication method? And when do we use the tops x tops, bottoms x bottoms? Like on the 1st step of the first question and the 5th step of the same question.
Good evening sir. I tried to work on some grade 11 questions. I am rewriting mathematics on November so know I am practicing trigonometry but I came across this trigonometry identity : Rcos(x-a)=cos(x)+tan(a).sin(x) Can you please explain how this identity works?
for the last question where we have to prove tan = sin/tan ; is attempted it before getting the steps and wrote it as a whole as cos/sin =tan/1 and had trouble making L.H.S= R.H.S PLEASE HELP , I am trying to master this concept for June examinations!

No because at this point Kevinmath is carrying my grades now! 😭💯
This man is incredible! He deserves more attention.
These questions were in my exam 👀 imagine my shock, thank you 😊
Oh wow, that is awesome! :)
Same😂
You are a genius I swear with consistent practice these would be way much easier and you showed that , thank you
Yeah this guy is helping me alot and I hope his channel keeps growing and he keeps helping us
You are the best math teacher in the whole entire world helping students 👏 love ya
Ur really a good teacher ,THANK YOU ×1MILLION!!!!
Pleasure!!! :)
Karabo you also here😂
From 20% to 47% .😢😮
Improvement is good where you at now...??
i swear you are a life saver you are literally my teacher
Thank you.
You explain it much better and in more simpler way❤️💯
Can you go over more of this please, THANK YOU
Will do my best!

😂😂😂😂
Thank you this helped so much for my upcoming exam
Pleasure :)
I WISH YOU THE MOST BLESSED BLESSINGS KEVIN😭
amazing video the last two i did on my own using the concept you had tough ...thank you so much ...i will subscribe now.
Awesome, I am so happy it helped!! :)
This man helps me all the time l watch this videos, you're the best Kevin
it’s tuesday night and i’m writing friday morning, am I cooked chat?
Lol how'd it go?

And then you split it up to become cos/sin - sin/cos which is then cos/sin - tan. Nice!! :)
2/ 11:53 minus 1+sin.x/cos.x both sides => cos.x/1+sin.x = 1-sin.x/cos.x, next multiply LCM both sides => cos^2x = 1 - sin^2x.
May the Lord Jesus bless you Mr Kevin❤🙏🙏❤you're a great help.
You are best you always do the interesting questions
Thank you so much 😀 All the best!!!
Thank you Kevin you're the best teacher ever 💎🥺🤞🏾

Very interesting indeed
I know you might not respond sir but thank you for changing my level2 into level6
Thank you so much, this is really helpful✌️❤️👊👍
Kevin the man you are🔥🔥🐐🐐

You the best sir you make my life easy😊
Hi thank you so much for your hard work.Are you gonna make videos about trig graphs
Hello! Not sure when I will be uploading to RUclips but you can checkout my course. Try it for free for 7 days. It has trig graphs :) www.kevinmathandscience.com/7dayW
Can you please do a video about Trigonometric Function🥺🙏
Noted! :)
When there's a division sign and we want to multiply, when do we use the flip over cross multiplication method? And when do we use the tops x tops, bottoms x bottoms? Like on the 1st step of the first question and the 5th step of the same question.
This is the best explanation
Legend Kevin!
Thank you soo much Kevin❤
if any DNC/DNK student comes here one day just know i was saved by kevin maths and science.........
Previous DNC student 😭🤞 ms exlerben needs to LEAVE
Good evening sir.

I am rewriting mathematics on November so know I am practicing trigonometry but I came across this trigonometry identity : Rcos(x-a)=cos(x)+tan(a).sin(x)
Can you please explain how this identity works?
Thank you so much

i am glad it helped.
Thank you so much 😭😭😭😭
Not all heroes wear capes
💯💯
I couldn’t understand, now I do
Awesome :)
Hey Kevin...why did you scratch out the ^2 in the first example
Someone give Kevin his Flowers🎉
thanks teach but aint you got any vids on general solutions
I will upload this week. Hope its not to late for a test!
Good bless you 💪
helped indeed😇😇😇
Awesome :)
thank u very much!!
for the last question where we have to prove tan = sin/tan ; is attempted it before getting the steps and wrote it as a whole as cos/sin =tan/1 and had trouble making L.H.S= R.H.S
PLEASE HELP , I am trying to master this concept for June examinations!
Second tip is wrong! be careful everybody!
Which second tip, and howcome?
i dont understand how you did that at 14:28. please explain oit or refer me to a video explaining it
❤❤🎉❤❤
Help
It's visible try to zoom pls🤓
Am lost when it comes to common fact😭😭
I don't understand
Do you have whatsapp groups
Hello
Can you please help with this sum
1-2sin^2x 1-tanx
------------------------ = -------------
1+2sinx.cosx 1+tanx
Thank you
Hello are you grade 11 or 12? It changes my approach.
