Escriba la función tan \(\theta\) en términos de cos \(\theta\) y \(\theta\) está en el tercer cuadrante. Select one: \(a.\) tan\(\theta\) = \sqrt{cos^2\theta + cos\theta} \(b.\) tan\(\theta\) = -cos^2\theta + 1 \(c.\) tan\(\theta\) = \frac{cos\theta + 1}{cos\theta} \(d.\) tan\(\theta\) = -\frac{\sqrt{1 - cos^2\theta}}{cos\theta}

Step 1
The tangent function is defined as the ratio of the y-coordinate to the x-coordinate of a point on the unit circle. In the third quadrant, the x-coordinate is negative and the y-coordinate is also negative. Show more…
