    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🥺

    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!!!

    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!! :)

    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.

    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.
