1-2 sin e cos 20-2 sin 40 = cos (20)
natka813 [3]

Answer:

No this is not the same as cos(2Ф)

Step-by-step explanation:

First I changed the cos^{2}Ф into 1-sin^{2}Ф

I then foiled the (1-2sin^{2}Ф)(1-sin^{2}Ф) and that resulted in 1-sin^{2}Ф-2sin^{2}Ф+2sin^{4}Ф

From there, I then cancelled the two 2sin^{4}Ф and combined like terms and was left with 1-3sin^{2}Ф

Now 1-3sin^{2}Ф ≠ cos(2Ф)
