Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x
Answer:

Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the area of the large square

step 2
Find the area of the smaller white square

step 3
Find the area of the blue region
Subtract the area of the smaller white square from the area of the larger square

step 4
Find the probability
we know that
To find out the probability that a point chosen at random is in the blue region, divided the area of the blue region by the area of the larger square
so

Simplify

Answer:6 x 103km = 618km and I believe Saturn is bigger than Earth so "Earth is approx. 6 x 103km" is a lie.
Step-by-step explanation:
