WebMay 25, 2024 · Take for example the number (1,-1). This means that sine has a negative sign. To check the cosine sign, we check the sign of the x coordinate of (1,-1). Since it is positive, the cosine is positive. Since tangent = sine/cosine and taking into account the law of signs, we have that tangent has a negative sign in this quadrant. WebSolution: Before we begin solving for the 3 double-angle values and 3 half-angle values, let us first find cos (α) and tan (α) since they will be helpful in our calculations. By using the Pythagorean relationship and the fact that cosine is negative and tangent is positive in Quadrant III, we can determine that cos (α) = -4/5 and tan (α) = 3/4.
