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]{cot

=4*(cos7x/sin7x)

a(x)=cos(7x)

b(x)=sin(7x)

c(x)=x

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??

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

what i did was

f(x)=4*[tex]\sqrt[3]{cot

^{8}(7x)}[/tex]=4*(cos7x/sin7x)

^{8/3}a(x)=cos(7x)

b(x)=sin(7x)

c(x)=x

^{8}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??
