Answer:
Step-by-step explanation:
We use the law of logarithms that says log A - log B = log (A/B)
ln |sin θ| − ln | cos θ| = ln |sin θ/ cos θ|
We use that the tan A = sin A/cosB
ln |sin θ/ cos θ| = ln |tan θ|
ln |tan θ| = ln |sin θ| − ln | cos θ|
ln |tan θ| = ln |sin θ/ cos θ|
ln |tan θ| = ln |tan θ|
