I just had a math test. It was incredibly hard! I donno why teachers do this! They learn us easy things and ask us hard questions.
I think I'll fail and I'm sooooo angry cause for the first time in collage i really have studied and its so unfair:/

    @irene the space between x^2+ z^2= a^2 and y^2+ z^2= a^2. This was the easiest question that i answered with multiple integral.
    But some question was about calculate the space between two surface and etc.
