Hi Sir , Just had an interesting question here , for the question at 17:02 , i took a more fun approach using herons formula which uses the perimeter of the triangle to give us the area ( its particularly helpful in those vector problems where instead of using the cosine rule or dot product, if you know all the vectors you can easily find the perimeter by finding the magnitude of each vector and use herons formula ) anyways as i was finding length of TS i got 29/5 and it does confuse me how one length of a side is exactly the area of the whole triangle ( i have used herons formula and gave me correct answer) do you think this is correlated to Pythagoras or smth along those lines . Apart from that this videos are incredibly convenient as i needed some succinct and quick revision for my MAT . Thank you again , ur sincerely amazing Sir.
Interesting! I know of Heron's Formula, but am not that familiar with it, so unsure about the connection between the length and the area in this case - perhaps just a coincidence? Good luck with your MAT!
Loving these types of videos- keep this series going 🙌
I’m loving these summary videos they save a lot of time
These videos are really helping, thank you!
You're a fantastic teacher sir. I wish you well.
Thank you so much, you too!
appreciate this playlist
Great stuff
You are a star
hopefully,y I pass my first As test with these vids 😂😂❤
Good luck!
Still coming up watching this videos even though i finished my a levels 😅
True dedication to supporting my channel, I love it haha

Yh we love coincidences, and thank you ill need all the luck for that test😅
