Given the periodic property of the cosine function, we can represent it as cos (450° mod 360°) = cos (90°). The angle 450°, coterminal to angle 90°, lies on the positive y-axis. Thus cos 450 degrees value = 0. Similarly, cos 450° can also be written as, cos 450 degrees = (450° + n × 360°), n ∈ Z. holiday inn wertzville rdWebCompute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
