**Reiny**, Wednesday, June 9, 2010 at 8:06pmif the cotØ < 0 then tanØ < 0

then Ø is in either II or IV

and since the cosØ = √2/2 (positive)

Ø is in I or IV

so Ø is in IV

the angle in standard position is 45°

(since cos45° = √2/2)

you should know the trig ratios of the 45° by heart.

so

sinØ = -√2/2

cscØ = -2/√2

cosØ = √2/2 --- the given value

secØ = 2/√2

tanØ = -1

cotØ = -1
