This is A level maths btw... A2 core maths 3 to be precise
this is what I did...
=2(2sinAcosA)(cos^2(A)-sin^2(A)
4sin(A)cos^3(A) - 4sin^3(A)cos(A)
I don't know if this is it or if I can go further with it considering it's only core math's 3 and this is under the topic double angle formulae

2sin(2A)cos(2A)=sin(4A)
