What are they actually asking me to find here?

    i am asked to present this function as a number of simple functions

    f(x)=4*[tex]\sqrt[3]{cot^8(7x)}[/tex]

    what i did was

    f(x)=4*[tex]\sqrt[3]{cot8(7x)}[/tex]
    =4*(cos7x/sin7x)8/3

    a(x)=cos(7x)
    b(x)=sin(7x)
    c(x)=x8
    d(x)=[tex]\sqrt[3]{x}[/tex]

    f(x)=4*d(c(a(x)/b(x)))

    but that just seem stupid to me, do you think that thats what im meant to do??

    Well, i guess that depends on what u call simple functions.
