In mathematics, trigonometric ratios are used to describe the relationships between the angles and side lengths of triangles. These ratios are essential in various mathematical and real-world applications, including physics, engineering, and navigation. In this article, we will explore the function that has the ratio $\frac{24}{25}$ .

The Basics of Trigonometric Ratios

Trigonometric ratios are defined as the ratio of the length of a side of a right triangle to the length of another side. The most common trigonometric ratios are:

Sine (sin): The ratio of the length of the side opposite the angle to the length of the hypotenuse.
Cosine (cos): The ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
Tangent (tan): The ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

The Given Ratio: $\frac{24}{25}$

The given ratio is $\frac{24}{25}$ . To determine which trigonometric function has this ratio, we need to analyze the possible combinations of side lengths that would result in this ratio.

Analyzing the Options

Let's analyze the options given:

A. $\tan \beta$ : The tangent function is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. If we assume that the side opposite the angle has a length of 24 and the side adjacent to the angle has a length of 25, then the tangent function would be $\tan \beta = \frac{24}{25}$ .

B. $\cos \beta$ : The cosine function is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. If we assume that the side adjacent to the angle has a length of 24 and the hypotenuse has a length of 25, then the cosine function would be $\cos \beta = \frac{24}{25}$ .

C. $\sin \theta$ : The sine function is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. If we assume that the side opposite the angle has a length of 24 and the hypotenuse has a length of 25, then the sine function would be $\sin \theta = \frac{24}{25}$ .

D. $\cos \theta$ : The cosine function is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. If we assume that the side adjacent to the angle has a length of 24 and the hypotenuse has a length of 25, then the cosine function would be $\cos \theta = \frac{24}{25}$ .

Conclusion

Based on the analysis of the options, we can conclude that the function that has the ratio $\frac{24}{25}$ is the tangent function, $\tan \beta$ . This is because the tangent function is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle, and the given ratio matches this definition.
