Mathematica Number and location of minima

  1. May 11, 2017 #1
    Take the function

    $$f(x) = ax^{2} + bx^{4} - c \cos(x/d),$$

    where ##a##, ##b##, ##c## and ##d## are arbitrary parameters.

    For some given choice of the parameters, how do you find the number of local minima of the function and the location of the minima?
