    Undergrad Why does the graph of x^x undefined for x is less than or equal to 0?

    The function works only in integer point. For each non integer point the function goes in Complex Set, and so isn't defined on real. Easilly, to avoid the calculator have problem on any other point lesser then 0, the programmer block each of that point with "does not exist" message. Fruthermore...

    Trigonometry ( high school level )

    Ok, I suggest you to try. Start with the simpliest solution: the equilateral one. You know the angles, does the equation work? In a second time you can try with right angled one. You know the first angle (say A) is 90° and the sum of the three angles have to be 180°, right? So, posing the...

    Question about relative angular velocity

    Hi, try to move the problem from angular speed to "linear" speed. The Earth moves with speed Ve, the KBO with speed V, so the relative speed between Earth and KBO is Ve - V. Now, the "linear" speed can be rewritten as the angular speed times the radius, so we can write the relative speed as...
