Identities Grade 11: Introduction and practice

[@mickeythabile3993]

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🥺

[@kevinmathscience]

Amazing!! :)

[@ecre5546]

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!!!

[@coddellc6339]

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. ❤❤❤

[@Juss-elos]

No because at this point Kevinmath is carrying my grades now! 😭💯

[@Tommy_lulu]

These questions were in my exam 👀 imagine my shock, thank you 😊

[@kevinmathscience]

Oh wow, that is awesome! :)

[@Justin-uw9yw]

Same😂

[@diremakweng6128]

This man is incredible! He deserves more attention.

[@davidmatsoso2814]

Yeah this guy is helping me alot and I hope his channel keeps growing and he keeps helping us

[@nikolai_nik9734]

You are a genius I swear with consistent practice these would be way much easier and you showed that , thank you

[@kerenkotolo]

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

[@sush1367]

You are the best math teacher in the whole entire world helping students 👏 love ya

[@siyabongakutloano9835]

From 20% to 47% .😢😮

[@N.E.S.W]

Improvement is good where you at now...??

This man helps me all the time l watch this videos, you're the best Kevin

[@sfundozondo2823]

amazing video the last two i did on my own using the concept you had tough ...thank you so much ...i will subscribe now.

[@kevinmathscience]

Awesome, I am so happy it helped!! :)

[@nkululekomicheal6155]

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

[@kevinmathscience]

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!! :)

[@BaoLe-vt7si]

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.

[@asisipholengisi8188]

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.

[@Carine.Bukasa-jp8lo]

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?

[@sohailhusain1700]

thank you so much this helped me alot

[@kevinmathscience]

Glad it helped!

[@Dailydosegoodshit]

Absolute legend!

[@prudenceezu9113]

Hi thank you so much for your hard work.Are you gonna make videos about trig graphs

[@kevinmathscience]

Hello! Not sure when I will be uploading to KZbin but you can checkout my course. Try it for free for 7 days. It has trig graphs :) www.kevinmathandscience.com/7dayW

[@keke_x]

Can you please do a video about Trigonometric Function🥺🙏

[@kevinmathscience]

Noted! :)

[@Promise0529]

Hey Kevin...why did you scratch out the ^2 in the first example

[@sizwekhumalo7829]

You are best you always do the interesting questions

[@kevinmathscience]

[@majurpanchol1335]

Very interesting indeed

[@Rea.M]

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!
