Presumably by "COS" you mean Carbonyl Sulfide. US-EPA lists carbonyl sulfide as a "hazardous air pollutant". So presumably emitters of this compound (other than cabbage farmers) are required to self measure, and describe how they are controlling its emission. I find no direct reference to a limit on emissions.
Epa and Emissions
The limit does not exist.
cos(5/n) = cos(0) --> 1
I'm sorry the question is not correctly displayed. If f(x) = cos(2x).cos(4x).cos(6x).cos(8x).cos(10x) then, find the limit of {1 - [f(x)]^3}/[5(sinx)^2] as x tends to 0 (zero).
Of coarse. EPA emmissions.

No, the EPA standard is not based on brake horsepower. Instead, the Environmental Protection Agency (EPA) sets emissions standards based on various factors, including vehicle type, weight, and fuel type. These standards aim to limit pollutants such as carbon monoxide, nitrogen oxides, and particulate matter, rather than focusing on the engine's power output.
The answer is undefined becaus infinite has no limit.
tan x = sin x / cos x, so:lim (tan x / x) = lim (sin x / x cos x). Since it is known that the limit of sin x / x = 1, you have lim 1 / cos x = 1 (since cos 0 = 1).tan x = sin x / cos x, so:lim (tan x / x) = lim (sin x / x cos x). Since it is known that the limit of sin x / x = 1, you have lim 1 / cos x = 1 (since cos 0 = 1).tan x = sin x / cos x, so:lim (tan x / x) = lim (sin x / x cos x). Since it is known that the limit of sin x / x = 1, you have lim 1 / cos x = 1 (since cos 0 = 1).tan x = sin x / cos x, so:lim (tan x / x) = lim (sin x / x cos x). Since it is known that the limit of sin x / x = 1, you have lim 1 / cos x = 1 (since cos 0 = 1).
The limit of ( \frac{x}{\cot x} ) as ( x ) approaches 0 can be evaluated using the fact that ( \cot x = \frac{\cos x}{\sin x} ). Therefore, we can rewrite the limit as ( \frac{x \sin x}{\cos x} ). As ( x ) approaches 0, ( \sin x ) approaches ( x ) and ( \cos x ) approaches 1. Thus, the limit is ( \lim_{x \to 0} \frac{x^2}{\cos x} = 0 ).
toxic chemicals
The Clean Air Act of 1970 was passed to limit auto emissions and improve air quality in the United States. This landmark legislation established national air quality standards and empowered the Environmental Protection Agency (EPA) to regulate pollutants emitted by vehicles. It aimed to reduce the environmental and health impacts of air pollution, including emissions from automobiles. The Act has been amended several times to strengthen air quality protections and address emerging environmental issues.
