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.
y = arcsin( cos 48 ); arcsin may be seen as sin-1 on your calculator.

hi,the value of cos 60 is 1/2
if sec A-tan A = a/b find the value of cos A.
cos(195) = -0.965925826289
If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
Cos(22.5)=0.9238795325
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.
-55
-0.432177945
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 315 degrees is 4th quadrant same as cos (-45) degrees which is +0.7071
