Step-by-step explanation:

The cosine function, along with sine and tangent, is one of the three most common trigonometric functions. In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as 'cos'.

In any right angled triangle, for any angle:

The sine of the angle = the length of the opposite side

the length of the hypotenuse

The cosine of the angle = the length of the adjacent side

the length of the hypotenuse

The tangent of the angle = the length of the opposite side

the length of the adjacent side

So in shorthand notation:

sin = o/h cos = a/h tan = o/a
