What Is Cos 1 Equal To? [Solved]
The value of cos 1 degrees can be calculated by constructing an angle of 1° with the x-axis, and then finding the coordinates of the corresponding point (0.9998, 0.0175) on the unit circle. The value of cos 1° is equal to the x-coordinate (0.9998). ∴ cos 1° = 0.9998.
Why does sine squared plus cosine squared equal 1?
Have you ever been told that sine squared plus
