Question

what quadrant is sinθ>0 and cosθ< 0

Answer 1

1st quadrant for sin theta <0 and 3rd quadrant for cos theta <0

Answer 2

Excuse me; 2nd* quadrant for cos theta <0

Answer 3

So what would both be located in?

Answer 4

1st Quadrant:
- sin θ > 0
- cos θ > 0
- tan θ > 0

2nd Quadrant:
- sin θ > 0
- cos θ < 0
- tan θ < 0

3rd Quadrant:
- sin θ < 0
- cos θ < 0
- tan θ > 0

4th Quadrant:
- sin θ < 0
- cos θ > 0
- tan θ < 0

u can remember it by labelling each quadrant a letter and writing a sentence for it
e.g. ASTC= All Stations To Central
A= all angles > 0
S= only sin θ > 0
T= only tan θ > 0
C= only cos θ > 0

Answer 5

Try to figure it out by using this. Location of quadrant is where I would get stuck on.

Answer 6

thanks

Answer 7

Just got it. Both should be in the 2nd Quadrant.
