    Neutron Dipole Moment: Parity, Time Reversal Symmetry

    Hi, I have been wondering about a neutron dipole moment, though hypothetical what symmetries would it be violating, wouldn't it be Parity and Time reversal? If this were to be true, would it therefore make the statement below false and the word "inverted" would imply parity? "T is the law of...

    What is the Problem with Calculating Roots of a Quartic Equation?

    I am not at all an expert on quadratic functions, but i will just input what mathematica (you could also check this at wolfram alpha) has given as a result: x=1.20784 or x=1.56122-0.165428 i or x=1.56122+0.165428 i or x=1.9146 , which if then we use the plot we can see that the intersects...

    Why are you starting a new thread? Is there something new you are asking?

    Homework Statement The curve C has equation y=k x^3-x^2+x-5 where k is a constant. A) Find the derivative of the function with respect to x The point A with x-coordinate -\frac{1}{2} lies on C. The tangent to C at A is parallel to the line with equation 2 y-7 x+1=0 . Find...

    Solving a Math Problem: Find k and y-coordinate of Point A on Curve C

    So, as far as i understand it, the slope of the line that is tangent to C at point A (-1/2). The second equation given is parallel to the first derivative of C when x=-1/2 My first thought was to do this: 3 k x^2-2 x+1=2 y+\frac{9}{2} which is the same as y'\left(-\frac{1}{2}\right) =2...

    Gamma Distribution Confidence Interval

    So can i use another distribution to approximate the parameters (e.g the mean) of the gamma dist? Thanks

    Gamma Distribution Confidence Interval

    How would you go about finding the confidence interval for the parameters of the gamma distribution? I have had a look online and haven't found anything with the answer... Thanks
