WebExplanation: For cos 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 45° value = 1/√2 or 0.7071067. . . ⇒ cos 45° = cos 405° = cos 765°, and so on. Note: Since, cosine is an even function, the value of cos (-45°) = cos (45°). WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations.
