How do you use calculator to find cos degrees?
To find the cosine of an angle in degrees using a calculator, first ensure that the calculator is set to degree mode (not radians). Enter the angle in degrees, then press the "cos" button. The calculator will display the cosine value for that angle. For example, to find cos(60°), input 60, select "cos," and the result will be 0.5.
What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
What is the reference angle to a 140 degree angle?
60
What is the ratio of the cosine of an angle?
Fora right angle triangle: cosine angle = adjacent/hypotenuse
What ratio correctly describes the cosine function?
The cosine of theta is adjacent over hypotenuse, given a right triangle, theta not being the 90 degree angle, adjacent not being the hypotenuse, and theta being the angle between adjacent and hypotenuse. In a unit triangle, i.e. in a unit circle circumscribed with radius one, and theta and the center of the circle at the origin, cosine of theta is X.
What is the cosine of a 59 degree angle?
cosine(59 degrees) = 0.51504 (rounded)
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
What is the secant of 60 degrees?
The secant of an angle is the reciprocal of the cosine of that angle. For 60 degrees, the cosine is 0.5, so the secant is 1 divided by 0.5. Therefore, the secant of 60 degrees is 2.
At what angle measure are the sin and the cosine equal?
45 degree

Is 60 degree angle and 60 degree angle congruent?
yes
How is a 30 degree angle related to a 60 degree anlge?
a 60 degree angle is twice the size of a 30 degree angle.
What is the cosine of a 50 degree angle?
cos(50) = 0.6428 (rounded)
What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
What is the cosine of a 65 degree angle?
Cos(65 deg) = 0.4226 approx.
When current and voltage are 90 degrees out of phase what is the power?
Power in an electric, AC circuit is the product of Volts, Amps, and the Cosine of the angle that separates them. When the Amps lag behind the Volts by 60 degrees, the product of Volts, Amps, and the Cosine of the angle between them provides half the power that would otherwise be available without the 60 degree angle. At 60 degrees, the cosine is 0.5 and at 90 degrees it is zero. So the product of Volts and Amps whenever they are 90 degrees out of phase will result in zero power.
How many minutes are in a degree?
There are 60 minutes of angle in one degree of angle.
