Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.

Answer: 82
Step-by-step explanation:
The formula to find the sample size is given by :-

, where E = Margin of error.
= Population standard deviation for the prior study.
As per given , we have
gallons.
Margin of error : E= 110 gallons
Critical value for 99% confidence level = z* = 2.576
Then, the required sample size : 
{Rounded to the nearest integer.}
Hence, the minimum sample size = 82
