limit of (1-cosx)/x as x approaches 0 =0

A new video with another limit proof!

We can use the last proof of 

limit of sinx/x as x approaches 0 =1

 to help prove another "famous" proof

 limit of (1-cosx)/x as x approaches 0 = 0

I used my new tablet and an easy to use program called Skitch to create this.
