1-104.

Determine the *exact* value(s) of *x *in the domain 0 ≤ *x* ≤ 2*π* if: Homework Help ✎

sin(

*x*) = −, tan( *x*) > 0cot(

*x*) is undefined, cos(*x*) > 0csc(

*x*) =, sin( *x*) > cos(*x*)

In which quadrant of the unit circle is sine negative and tangent positive?

Refer to the hint in part (a). And recall that cotangent is the reciprocal of tangent.

For cot*x* to be undefined, its denominator must equal 0.

Refer to the hint in part (a). And recall that cosecant is the reciprocal of sine.
