Find all the angles between 0°, 360° where tan(theta) = -1

Find all the angles between 0°, 360° where tan(theta) = -1

Find all the angles exactly between 0° and 360° for which \(\displaystyle \tan{(\theta)}\, =\, -1\)

From the table we created in class and the notes I have I'm thinking the answer is that there are none? I'm not sure what to do with this. Is there a formula I'm not aware of?

 

[skeeter]

tan(x) = sin(x)/cos(x) ... where in the domain do sin(x) and cos(x) have opposite values?

 

[susaneholt]

domain?

domain? not sure...we have no notes about this. The homework from the book I have no trouble with....this is something he gave us on the side...

 

[skeeter]

the domain is the values for x ... between 0 and 360 as stated in your initial post.

Ok, well, still don't get it.....guess I'll have to pass on this one...thanks anyway...I'll have to ask instructor to explain more...
