    Graduate What is the Nature of Singularity in the Function f(x)=exp(-1/z)?

    what is the nature of singularity of the function f(x)=exp(-1/z) where z is a complex number? now i arrive at two different results by progressing in two different ways. 1) if we expand the series f(z)=1-1/z+1/2!(z^2)-... then i can say that z=0 is an essential singularity. 2) now again if i...

    Time period of a conical pendulum by D'Alembert's principle

    Use Cartesian co-ordinates. Take the length of the string=constant to be the constraint eq. Find delta(z). Substitute values in d'alemberts', put delta (z). You'll be able to find the time period
