    taylor expansion of given function

    Write down the Taylor expansion about (0,0) up to, and including, terms
    of second order for the following two functions:
    i) log(y+cos2x), ii) (cosy)(2+x)^{\frac{1}{3}}

    Why are you not even attempting these problems? It's almost impossible to give any hints or help without knowing exactly what difficulty you have with a problem and we need to see what you have tried to determine that.

    You will need the first and second (partial) derivatives of the functions evaluated at (0,0), what do you get for the derivatives?
