Let's first get the representation of tan
We also need to understand how to convert radians to degrees
[tex]\begin{gathered} \frac{\pi}{2}=90^0 \\ \pi=180^0 \\ \frac{3\pi}{2}=270^0 \\ 2\pi=360^0 \end{gathered}[/tex]
For question 1
since tan > 1
It must be in either first quadrant or third quadrant as shown in the diagram above
[tex]\begin{gathered} \text{ } \\ \frac{\pi}{4}<\emptyset\text{ < }\frac{\pi}{2} \\ or\text{ } \\ \frac{5\pi}{4}<\phi\text{ <}\frac{3\pi}{2} \\ \end{gathered}[/tex]
