WebWhat is a basic trigonometric equation? A basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a How to convert radians to degrees? The formula to … WebFor cos 1 degrees, the angle 1° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 1° value = 0.9998476. . . Since the cosine function is a periodic function, we can represent cos 1° as, cos 1 degrees = cos (1° + n × 360°), n ∈ Z. ⇒ cos 1° = cos 361° = cos 721°, and so on. plc mines and minerals
