Question

For what x-value(s) does sin(x) = -1?

Answer 1

If you look at the unit circle, you see that x has to be 270 degrees in order for the sin(x) to be -1. Or in general form it can be\[x=270\pm360 degrees\]

Answer 2

I have two options that have 270 in it... Is it either of these -270°, -90°, 90°, and 270°

or -270°, -90°, 0°, 90°, and 270°
