Question
secθ>0 and cscθ<0 means that ∠θ is located in the
second quadrant
third quadrant
fourth quadrant
first quadrant
Recordemos que \( \sec\theta=\frac{1}{\cos\theta} \) y \( \csc\theta=\frac{1}{\sin\theta} \). Si \( \sec\theta>0 \), entonces \( \cos\theta>0 \). Si \( \csc\theta < 0 \), entonces \( \sin\theta<0 \). En el primer cuadrante \( \sin\theta>0 \) y \( \cos\theta>0 \), en el segundo \( \sin\theta>0 \) y \( \cos\theta < 0 \), en el tercero \( \sin\theta<0 \) y \( \cos\theta < 0 \), y en el cuarto \( \sin\theta<0 \) y \( \cos\theta>0 \).
