What is cos formula?
The cosine formulas talk about the cosine (cos) function. … Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where “adjacent side” is the side adjacent to the angle x, and “hypotenuse” is the longest side (the side opposite to the right angle) of the triangle.
Can Cos equal 1?
1 Expert Answer 1) In the unit circle the x represent the cosine of the function and the y represent the sine of the trigonometric function. 2) Looking at the unit circle I noticed that cos(x) =1, corresponds to 360°. in other words cos (360º) =1, the answer is x=360º or x=2π radians.
