Trigonometry and Limits: limit of sin(x)/x as x goes to 0

in hive-196037 •  2 years ago  (edited)


In this video I show a geometric proof of this very useful limit of sin(x)/x as x goes to 0. I will use this in later videos to prove many trig derivatives and integrals.

I don't always go over limits of trigonometric functions but when I do I usually apply the squeeze theorem in the proof ;)
