Please type this as 2(sin 2x)^2=2 <span>2sin^2 2x=2 is confusing.
Reducing this expression: (sin 2x)^2 = 1
Taking the sqrt of both sides, sin 2x = plus or minus 1
If sin 2x = 1, then 2x must be pi/2 or 3pi/2, and so x must be pi/4 or 3pi/4.
Now you do this for sin 2x = -1.</span>
Answer:
-3f - 10
Step-by-step explanation:
-1 times 10 = -10
-1f times 3f = -3f
Sorry if this isn't right.
Answer:
The answer would be 0.8, 8 squares filled.
Step-by-step explanation:
This is because 0.4*2 is 0.8 and that out of a grid of 10 means that 8 cubes would be shaded.
Answer:
