  1. Greetings from Idaho! I’m bored to death at work so I decided to check out your
    blog on my iphone during lunch break. I enjoy the info you provide here
    and can’t wait to take a look when I get home.
    I’m shocked at how fast your blog loaded on my phone
    .. I’m not even using WIFI, just 3G .. Anyhow, superb site!

  2. Write more, thats all I have to say. Literally, it seems as though you relied on the video to make your point.

    You clearly know what youre talking about, why throw away your intelligence
    on just posting videos to your site when you could be giving us
    something informative to read?

  3. Excellent post. Keep writing such kind of information on your site.
    Im really impressed by your site.
    Hey there, You’ve performed an excellent job. I’ll definitely digg it and in my view recommend
    to my friends. I’m confident they’ll be benefited from this web site.

  4. zamienić licznik z mianownikiem i zastąpić tg ctg np. ctg(atfa+beta)=ctg(alfa)ctg(beta)-1/ctg(alfa)+ctg(beta)
