WebIf A is given then we can easily find the quadrant in which A/2 lies. Therefore, using the rule of “All, sin, tan, cos” we can find the exact signs of sin A/2, cos A/2 and tan A/2. In other words, if the value of cos A is given then A can have infinite number of values. Hence, it is not possible to find the exact quadrant in which A/2 will lie.
