Can L’hospital rule work for finding limits of complex functions

  1. Mar 21, 2012 #1
    I know for multivariable function it doesn’t work. However if the function is in the form of f(z) and z is the only variables shown. Can I use it?

    Thanks

    Yes - as long as the necessary derivatives are continuous at the z in question.
