Determine the quadrant in which each lies:

Question

sec0<0,cot0<0
sin0<0,tan0>0

Answer 1

Use "All Students Take Calculus" to find which of the functions are positive in which quadrant. The positive quadrants are for:

S|A
----
T|C

To find which quadrant will have sec<0 and cot<0, you look up the quadrant where cos<0 and tan<0.
For cos<0, it will be either quad.II or quad.III.
For tan<0, it will be either quad.II or quad.IV.
So quadrant II will satisfy both conditions.
