The cosine of 16 degrees is approximately 0.9613. This value can be found using a scientific calculator or trigonometric tables. In the context of a right triangle, it represents the ratio of the length of the adjacent side to the hypotenuse when the angle is 16 degrees.
It is: cos(0) = 1
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.
In radians: cos(42) = - 0.399965315 ---------------------- In degrees: cos(42) = 0.7431448255 ----------------------
cos(42o) = 0.7431448255 ==============( approximately 37/50 )
cos(51°) ~ 0.63
The cosine of 16 degrees is approximately 0.9613. This value can be found using a scientific calculator or trigonometric tables. In contexts such as physics or engineering, cosine values are often used to resolve components of forces or analyze wave functions.
The value of cos 40 degrees is approximately 0.766.
It is: cos(0) = 1
cos(16 = 0.9612616959
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.
cos 315 degrees is 4th quadrant same as cos (-45) degrees which is +0.7071
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(495) = cos(495-360) = cos(135) = -cos(180-135) = -cos(45) = -sqrt(1/2) or -1/sqrt(2)
I can answer if you tell me what cos means.
Cos(22.5)=0.9238795325
cos(25o) = 0.906307787 ==========
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
