    Hi all,

    I was reading the article in the link below:

    http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/schmitt.html

    Can someone please explain to me how he derived to the last step? I cannot clearly understand how he proceeded from one step to the others in the equation below.

    Any help would be highly appreciated.
    Thanks and sorry for my poor English.

    I will excuse your English if you excuse my spidery hand writing.;)
    (Actually your English seems fine).

    Have a look at this:
