Hello guys,
I'm currently reading through K&K Intro to Mechanics book, and I'm on page 26 where I encounter a bit odd derivation.

I'm rather lost on this part. I don't know which sketch corresponds to this equation....
Using the angle ##\delta \theta## defined in the sketch,
##|\delta A| = 2A \sin{\frac{\delta \theta}{2}}##
