Hello Mr.Poliakoff, thankyou for this simple and direct video. Just started tutoring a kid recently so I often find myself re-touching some basics. You have been a big help :)

Straight to the point! Thank you very much sir❤ you deserved a sub!

This was the most helpful video I found for this, I have my chemistry exam tomorrow! :o

Thank you so much for this I was puzzled on a question in biology gcse combined science and this helped me a lot. Thank you

Oh so that's how you must position the ruler. I always did it from underneath the point rather than from above which is why I must be getting wrong measurements all the time. Thanks for the video!

this is very helpful, thank you very much

I've a Chemistry exam tomorrow, thank you 😊

thanks for video, but how do i know what angle the ruler is at the tanget, it can be at the point but still different angles?

Thanks ...tomorrow...is my exam...just wanted have a glance on it before going further...god save me tomorrow..

In time vs concentration graph instantaneous rate equals to the 1) Area of graph. 2) X axis. 3) Y axis 4) slope of the tangent??

How do I know how long to draw the tangent line ? Because it will alter my ends results

How would you do 30 seconds ? Do I just put a straight line or let it go straight through the lines?

bro you literally saved my life, thank youu🫶🏾
