WebRomans 1:20). If we want knowledge beyond what our senses can tell us—and we most certainly do—we are to seek that information from God, and from God alone. The Holy Spirit alone has written the revelation of God in the Bible. Clairvoyants, psychics, a… WebExplanation: For cos 60 degrees, the angle 60° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 60° value = 1/2 or 0.5. Since the cosine function is a periodic function, we can represent cos 60° as, cos 60 degrees = cos (60° + n × 360°), n ∈ Z. ⇒ cos 60° = cos 420° = cos ...
