In which quadrant does θ lie if the following statements are true:secant, theta, is greater than, 0, and , cosecant, theta, is less than, 0secθ>0 and cscθ<0
Question
In which quadrant does θ lie if the following statements are true:secant, theta, is greater than, 0, and , cosecant, theta, is less than, 0secθ>0 and cscθ<0
Solution
The secant function, sec(θ), is positive in the first and fourth quadrants. The cosecant function, csc(θ), is negative in the third and fourth quadrants. Therefore, if sec(θ) > 0 and csc(θ) < 0, then θ must lie in the fourth quadrant.
