    one-parameter weibull distribution

    i need to find the E[x] and E[x^2] for the one-dimential weibull distribution.
    the pdf is given by:
    2ax*e^(-ax^2), where a is the parameter

    i can only integrate it by introducing the erf function. and i cant find anything online about thie one-parameter case

    thanks

    Read the attachment for the general case. Make the necessary substitutions for your particular integral.
