Rewrite tan(x) as sin(x)/cos(x)
Use substitution: let u = cos(x), then du = -sin(x)dx
Integrate
Same as tanx - appears in activation functions and optimization landscapes.
The integral of tan(x) is -\ln|\cos(x)| + C, where C is the constant of integration.
Follow the step-by-step solution above, which uses standard integration techniques.
