The adjacent side or base of the triangle.
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
It is a non-linear function of theta.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
mathematical equation
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.
The cosine function on a right triangle is Adjacent leg divided by the hypotenuse of the triangle.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
Fora right angle triangle: cosine angle = adjacent/hypotenuse
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
It is a non-linear function of theta.
cosine
Use either the Sine or Cosine rules depending on the information you know about the triangle.
hypotenuse.
mathematical equation
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.
put in cosine in your calculator and then take the cosine of the length of the adjacent length over the length of the hypotenuses length
