R sin (theta) is the height of the triangle (using right angled trig to calculate the height). So 1/2 r² sin theta is what you get when you put the height as given above and the base (which is just r) into the area of a triangle formula:A =1/2 base * height
I knew these with degrees but never with radians. I instantly got this! You’re a great teacher
Hello sir, I am from INDIA I love your teaching
Sir you are one of great teacher for me
Commenting before watching...
Tnx from Ethiopia
Sir very impressive
Love your channel so much sir.
good teaching..
Thank you sir from MÉXICO, VER n(ice)
Sandar ❤️♥️♥️♥️
Thank you sir
i sont know why but for some reason these videos maje me feel calm
Looks like an angle of 120° or 1/3 one third.
What app is he using on the iPad?
notability
i didnot get the last part (minus traingle area) 1/2· r^2 sin ø? anyone explain, or recommend me certain video where someone explains?

luv u babe
Me:
I do not understand geometry
Literally everyone else:
Omg I love this, I get this.
:/ I feel left out :-:
ok
Not enough contrast
I learnt this in year 7.
Congrats! You are a legend!!!!!
