To find the derivative of the function f(x) = csc(x), where csc(x) represents the cosecant of x, we can use the quotient rule
To find the derivative of the function f(x) = csc(x), where csc(x) represents the cosecant of x, we can use the quotient rule.
The quotient rule gives us the formula for finding the derivative of a function f(x) = g(x)/h(x) as:
f'(x) = (g'(x) * h(x) – g(x) * h'(x)) / [h(x)]^2
In this case, g(x) = 1 and h(x) = sin(x), since csc(x) is equal to 1/sin(x).
Using this information, let’s find the derivative of f(x) = csc(x):
g'(x) = 0 (the derivative of a constant is zero)
h'(x) = cos(x) (the derivative of sin(x) is cos(x) using the chain rule)
Plugging these values into the quotient rule formula:
f'(x) = (0 * sin(x) – 1 * cos(x)) / [sin(x)]^2
Simplifying:
f'(x) = -cos(x) / (sin(x))^2
Therefore, the derivative of csc(x) with respect to x is -cos(x) / (sin(x))^2.
