Identify the quadrant or quadrants in which an angle A in standard position must be if csc A > 0 and tan A < 0?

Angle A must be located in Quadrant II, as csc A > 0 means that the sine function (and hence csc A) is positive, and tan A < 0 means that the tangent function is negative. In Quadrant II, both sine and tangent are positive, while cosine is negative.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
