Hi
I'm just wondering if there are any radian formulas out there that I could put in my notes,
formulas like
arc length = r $\theta$
area of segment = $\frac{R^2}{2}(\theta - sin\theta)$
area of sector = $\frac{1}{2}R^2\theta$
length of chord...(this i dont know) ...etc

if you guys could help out, i'd be very grateful!

PSalso, how does one derive the area of segment?

area of a circle is 0.5(theta+sin(2theta) theta belongs to -pi/2 to pi/2
sorry I dont know latex
