Find the intersection points of the function

#### Explanation:

**1. Intersection with y-axis**

Let

*On the function #sinx#, where does #x=-45°# or #315°#?*

Using the unit circle,

Therefore intersection with y-axis is at point

**2. Intersection with x-axis**

Let

*On the function #sinx#, when does #sinx=0#?*

Using the unit circle,

Therefore

However, 405° is not inside the domain so x cannot be greater than 360° so this number is excluded. All other numbers lie in between 0 and 360 so they're fine.

Therefore intersection with x-axis is at points
