What is the cosine of a 60 degree angle?
Cosine is 0.5
What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
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 cosine of 0 degree?
It is 1.
What is the cosine of a 60 degree angle?
Cosine is 0.5
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
At what angle measure are the sin and the cosine equal?
45 degree
What is the cosine of a 50 degree angle?
cos(50) = 0.6428 (rounded)
What is the cosine of a 65 degree angle?
Cos(65 deg) = 0.4226 approx.
What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
How do you find the sec of a 38 degree angle?
Find the cosine of 38 degrees and then find its reciprocal.
What is the ratio of the cosine of an angle?
Fora right angle triangle: cosine angle = adjacent/hypotenuse
What is the relevance of the number 1.414 to a 45 degree angle?
The number 1.414... (square root of 2) is two times the cosine or sine of a 45 degree angle. The reason for this is that for a 45 degree angle, the two sides are cosine and sine, they are equal, and if you solve using the Pythagorean theorem with a hypotenuse of 1, the two sides are each (21/2)/2.
What is a 23 degree angle called?
A 23 degree angle is an acute angle, as is any angle less than 90 degrees but more than 0 degrees.
What is the cosine function about?
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
