Determining the quadrants in which the tangent is positive or
Determining the quadrants in which the tangent is positive or negative By definition of the tangent: tangent is the ratio of sine to cosine. Therefore, the sign of the tangent will be positive in the quadrants where the sine and cosine have the same signs.
