The Limit (do not use L'Hospital rule)

The limit of sin(x)/x as x goes to 0,
Proof of the derivative of sin(x), https://youtu.be/j1n6AMuMQso

No, we cannot use Taylor series for sin(x) since we need derivative as well. https://youtu.be/zgwUMJOXwDM

The limit as x goes to 0 of sin(x)/x ,
Geometric proof of sin(x)/x goes to 1 as x goes to 0,
don't use l'hospital's rule,
avoid circular reasoning,
Squeeze theorem example,
