To evaluate the integral ∫cot(x) dx, we can use the substitution method.
Let’s start by considering the definition of the cotangent function:
cot(x) = cos(x)/sin(x)
Now, let’s make the substitution u = sin(x). This implies that du/dx = cos(x), or equivalently, dx = du/cos(x).
Substituting these expressions into the integral, we have:
∫cot(x) dx = ∫(cos(x)/sin(x)) dx
= ∫(cos(x)/(u)) (du/cos (x))
Notice that the cos(x) terms cancel out, leaving us with:
∫(1/u) du
Now, we can proceed to integrate:
∫(1/u) du = ln|u| + C
Finally, substituting back u = sin(x), we get:
∫cot(x) dx = ln|sin(x)| + C
Therefore, the integral of cot(x) is ln|sin(x)| + C, where C is the constant of integration.
