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)
iF the angle of 72 is measured in degrees, cos 72° ≈ 0.3090 If the angle of 72 is measured in radians, cos 72 rad ≈ −0.9673 If the angle of 72 is measured in gradians, cos 72 grad ≈ 0.4258
The value of cos 40 degrees is approximately 0.766.
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
Cos(22.5)=0.9238795325
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.
cos(195) = -0.965925826289
hi,the value of cos 60 is 1/2
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.
