Rewrite with only sin x and cos x.
sin 2x - cos 2x
a. 2 sinx cosx - 1 + 2 sin^2x
b. 2 sin x cos^2x - 1 + 2 sin^2x
c. 2 sin x cos^2x - sin x + 1 - 2 sin^2x
d. 2 sin x cos^2x - 1 - 2 sin^2x

  A. 2·sin(x)·cos(x) - 1 + 2·sin^2(x)

Step-by-step explanation:

The double angle identities can be use directly:

The difference of these is ...

  sin(2x) -cos(2x) = 2sin(x)cos(x) -(1 -2sin^2(x)) = 2sin(x)cos(x) -1 +2sin^2(x)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
