Answer:
(0, π/4] ∪ (π, 5π/4]
Step-by-step explanation:
Multiplying by 2 gives ...
cot(x) ≥ 1
The cotangent function decreases from ∞ to 1 in the domain (0, π/4], and again in the domain (π, 5π/4]. The solution is the union of these two intervals.
x ∈ (0, π/4] ∪ (π, 5π/4]
_____
(a, b] is interval notation for a < x ≤ b
I need help on that to. We have a test tomorrow and I can't figure it out and I need help:(
The ratio is 4:6
I’m not really sure what the question was
The median is 6. What you do is list all the numbers in order and cross one on each side out until your left with one.
A) No, because 62 + 9 = 122
