Answer on Question #58897 – Math – Trigonometry

Question

If $\sin \theta > 0$ and $\cos \theta > 0$, then the terminal point determined by $\theta$ is in:

- quadrant 1.

- quadrant 3.

- quadrant 2.

- quadrant 4.

Answer: Quadrant 1.

Question

If $\sec \theta = \frac{5}{3}$ and the terminal point determined by $\theta$ is in quadrant 4, then:

- $\sin \theta = -\frac{2}{5}$

- $\cos \theta = \frac{3}{5}$

- $\csc \theta = -\frac{5}{4}$

- $\tan \theta = \frac{4}{3}$

Answer: $\cos \theta = \frac{3}{5}$, $\csc \theta = -5/4$.
