    Maximum of exponential function

    Yup that is exactly what I was doing wrong! :\ Thank you

    Maximum of exponential function

    Sorry was going to edit and accidentally deleted : I get: (1-nt)e^(nt) set equal to 0 and solve: (1-nt)e^(nt)=0 -> 1-nt=0 -> n=1/t I'm missing my e^1 in the denominator though

    Maximum of exponential function

    That all makes sense my issue is how do I get the e^1 in the denominator? because isn't e^(-nt)= 0 a non real answer?

    Maximum of exponential function

    If we set it equal to zero and solve that will be our maximum

    Maximum of exponential function

    Homework Statement given the formula m=n*e^(-nt) show that the maximum of this curve is at m=1/(t*e^(1)). 2. The attempt at a solution I can show this graphically but I am curious if it is possible to do it by hand?

    What Was the Initial Energy of a Positron Entering a Plastic Slab?

    This is the range of a beta particle in any medium that has an effective Z of <10 Also that second relationship is given to me. See image. The assumption we are making in this problem is that the electron will travel in a straight line through the medium. I know this isn't true at all but for...

    Affirmation. I know I am not suppose to use a beta spectrum here. I may be starting to convince myself 2.2 from the back of the book is actually wrong

    What Was the Initial Energy of a Positron Entering a Plastic Slab?

    This is a single mono-energetic particle. Shouldn't need a beta spectrum.

    What Was the Initial Energy of a Positron Entering a Plastic Slab?

    Homework Statement Q- a positron emerges normally from a 4-mm thick slab of plastic (density= 1.14g/cm^3) with an energy of 1.62 MeV. What is the energy of the particle when it entered the slab? Homework Equations Range when 0< T <= 2.5 MeV: R= .412+T^[1.27-.0954*ln(T)] where T is kinetic...
