Webb26 mars 2024 ยท I was able to use the power reduction formula and FOIL to reduce the cos 4 x But I am stuck. The length of the problem is complicating and I am not sure what can be combine. cos 4 x sin 2 x = ( 3 + 4 cos ( 2 x) + cos ( 4 x) 8) ( 1 โ cos ( 2 x) 2) algebra-precalculus trigonometry Share Cite Follow edited Mar 26, 2024 at 18:51
