Cos(22.5)=0.9238795325
If the angles are measured in radians then the answer is -0.2678
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
cos pi over four equals the square root of 2 over 2 This value can be found by looking at a unit circle. Cos indicates it is the x value of the point pi/4 which is (square root 2 over 2, square root 2 over 2)

The value of cos 40 degrees is approximately 0.766.
cos 34o ≈ 0.829 cos 34 = 0.86074
Cos(22.5)=0.9238795325
cos(25o) = 0.906307787 ==========
The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.
hi,the value of cos 60 is 1/2
cos(195) = -0.965925826289
When tan A = 815, sin A = 0.9999992 and cos A = 0.0012270 so that sin A + cos A*cos A*(1-cos A) = 1.00000075, approx.
