• How to reduce to this?

    In a worked out solution I am trying to figure out, this equation is reduced in one step. Can someone please break this up into a step by step simplification. (remember, j is the imaginary number as this is electrical engineering) (1/2)*(1/(1-(1/2)e^(jw))+e^(-jw)*(1)/(1-... = 0.75*e^(-jw)/(1.25-cos(w))

Menschen sind natürlich, egal ob gute oder schlechte, Lebewesen mit Merkwürdigkeit, Vorstellung und Bildung. Wir können viel von der Welt voll verstehen. Wir bauen Städte mit logischem Denkvermögen. Also, glauben wir von Haus aus Kausalität, während sie übereinstimmt mit, was wir gewöhnlich beobachten; alles hat sie ist Grundursache und Ursprung. Wir haben noch große Fragen nach der Welt und wir wissen es selbst nicht. „Woher kam uns?“ Man weißt und glaubt dass er ist von seiner Mutti gekommen und weißt auch, dass Sie von ihrer Mutti ist gekommen und so weiter, aber wo ist es entstanden und wo führt es hin?

  • English Grammar question: is it a University, or an University.?

    So one uses 'an' instead of 'a' when the article proceeds a noun that starts with a vowel. But when I say "I am an university student.", 'an' just doesn't sound right to me. Is this some sort of exception where one shouldn't use 'an'?
