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 (1-2 $sin^{2}$ Ф)(1- $sin^{2}$ Ф) and that resulted in 1- $sin^{2}$ Ф-2 $sin^{2}$ Ф+2 $sin^{4}$ Ф

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

Now 1-3 $sin^{2}$ Ф ≠ cos(2Ф)
