    Yes there must be an error. Thank you for that.

    MHB Finding z-(1/z) Given z=r(cosx+isinx)

    Your example makes sense, but that is a question in a book. Does it matter that z is in polar form?

    MHB Finding z-(1/z) Given z=r(cosx+isinx)

    No it is not z minus its conjugate. it is z minus (1 over z).

    MHB Integrate 3/(x(2-sqrt(x))) - No Partial Fractions

    integral of 3/(x(2-sqrt(x))) using u=sqrt(x)? But not using partial fractions

    Thank you Klaas. Did you use guess and check or numerical methods to get 0.824? Regards

    MHB Calculating New Emission Rate of Radioactive Source

    A radioactive source emits particles at an average rate of 1 pe second. Assume that the number of emissions follows a Poisson distribution. The emission rate changes such that the probability of 0 or 1 emission in 4 seconds becomes 0.8. What is the new rate? Thanks.
