To find the derivative of cot(x), we can use the quotient rule.
The cotangent function can be written as cos(x)/sin(x).
Let y = cot(x).
Then, we can rewrite cot(x) as y = cos(x)/sin(x).
Using the quotient rule, the derivative of cot(x) is given by:
dy/dx = (sin(x)(-sin(x)) – cos(x)(cos(x))) / (sin(x))^2
Simplifying the expression, we get:
dy/dx = (-sin^2(x) – cos^2(x)) / sin^2(x)
Using the trigonometric identity sin^2(x) + cos^2(x) = 1, we can simplify further:
dy/dx = (-1) / sin^2(x)
Thus, the derivative of cot(x) is:
dy/dx = -csc^2(x), where csc(x) represents the cosecant function (1/sin(x)).
