I can answer if you tell me what cos means.
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
cos(73°) = sin(17°) = ~0.29237
cos(60) = -0.95241298
Tan(60) = Sin(60)/ Cos(60) Sin(60) = sqrt(3)/2 Cos(60) = 1/2 Hence Sin(60) / Cos(60) = [sqrt(3) / 2] / [1/2} => sqrt(3) / 2 X 2/1 sqrt(3) Hence Tan(60) = sqrt(3) = Numerically = 1.732050808....

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
The value of cos 40 degrees is approximately 0.766.
cos(60) = 0.5 The simplest way is to use a calculator.
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.
