cos(60) = -0.95241298
Cos(60) = -0.95241 assuming that angles are measured in radians, as would be done by most mathematicians. If they are measured in degrees, the answer is 0.5
cos(60) = 0.57 x 60 x cos(60) = 7 x 30 = 210
Cos(22.5)=0.9238795325
The cos of 2pi is 360 degrees which is 1.

Cos(60) = -0.95241 assuming that angles are measured in radians, as would be done by most mathematicians. If they are measured in degrees, the answer is 0.5
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
cos(60) = 0.57 x 60 x cos(60) = 7 x 30 = 210
hi,the value of cos 60 is 1/2
cos(60) = 0.5 The simplest way is to use a calculator.
The value of cos 40 degrees is approximately 0.766.
Cos 43
It is: cos(0) = 1
30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
