Determine the cotangent of -37π^2. cot(-37π^2) =
Пошаговый ответ:
To find the cotangent of -37π^2, we first need to understand what the cotangent function is and then calculate it for the given value.
The cotangent function, denoted as cot(x), is the reciprocal of the tangent function. In trigonometry, it’s defined as:
cot(x) = 1 / tan(x)
To find cot(-37π^2), we’ll start by finding the tangent of -37π^2 and then take its reciprocal.

Find the Tangent of -37π^2:
To find the tangent of any angle, we can use the formula:
tan(x) = sin(x) / cos(x)
In this case, x = -37π^2. First, let’s find sin(-37π^2) and cos(-37π^2).
-
The sine function is periodic with a period of 2π, which means that sin(-37π^2) is equivalent to sin(0) because subtracting multiples of 2π from an angle doesn’t change its sine value. So, sin(-37π^2) = sin(0) = 0.
-
Similarly, the cosine function is also periodic with a period of 2π, so cos(-37π^2) is equivalent to cos(0), which equals 1.
Now, we can calculate tan(-37π^2):
tan(-37π^2) = sin(-37π^2) / cos(-37π^2) = 0 / 1 = 0

Find the Cotangent:
Now that we have found that tan(-37π^2) is 0, we can find cot(-37π^2) by taking the reciprocal:
cot(-37π^2) = 1 / tan(-37π^2) = 1 / 0
Division by zero is undefined in mathematics. So, cot(-37π^2) is undefined.
In conclusion, the cotangent of -37π^2 is undefined because the tangent of that angle is 0, and dividing by zero is not a valid mathematical operation.
