The value of cos 22° is equal to the x-coordinate (0.9272). ∴ cos 22° = 0.9272.
How do you find the value of cos 37 degrees?
FAQs on Cos 37 Degrees The value of cos 37 degrees can be calculated by constructing an angle of 37° with the x-axis, and then finding the coordinates of the corresponding point (0.7986, 0.6018) on the unit circle. The value of cos 37° is equal to the x-coordinate (0.7986). ∴ cos 37° = 0.7986.
How do you find the cosine on a calculator?
Press the “2nd” key and then press “Cos.” Your calculator should display “cos” with a negative 1 for an exponent and an open parentheses. Enter the cosine ratio. This is the adjacent side length divided by the hypotenuse length.
