Introduction
The sine function is a fundamental concept in trigonometry, used to describe the ratio of the length of the side opposite a given angle to the length of the hypotenuse in a right-angled triangle. In this article, we will explore the input and output values for determining the sine of $60^{\circ}$, a critical angle in trigonometry.
What is the Sine Function?
The sine function is a mathematical function that takes an angle as input and returns the ratio of the length of the side opposite the angle to the length of the hypotenuse. The sine function is denoted by the symbol $\sin$ and is defined as:
where $\theta$ is the angle and $\text{opposite}$ and $\text{hypotenuse}$ are the lengths of the sides of the right-angled triangle.
Input and Output Values for $60^{\circ}$
To determine the sine of $60^{\circ}$, we need to consider the input and output values. The input value is the angle $60^{\circ}$, and the output value is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Option A: Input $\frac{2}{\sqrt{3}}$; Output $60^{\circ}$
This option is incorrect because the input value is not the angle $60^{\circ}$, but rather a ratio of the length of the side opposite the angle to the length of the hypotenuse. The correct input value is the angle $60^{\circ}$, not the ratio.
Option B: Input $60^{\circ}$; Output $\frac{\sqrt{3}}{2}$
This option is correct because the input value is the angle $60^{\circ}$, and the output value is the ratio of the length of the side opposite the angle to the length of the hypotenuse. In a right-angled triangle with a $60^{\circ}$ angle, the ratio of the length of the side opposite the angle to the length of the hypotenuse is $\frac{\sqrt{3}}{2}$.
Why is Option B Correct?
Option B is correct because it correctly identifies the input and output values for determining the sine of $60^{\circ}$. The input value is the angle $60^{\circ}$, and the output value is the ratio of the length of the side opposite the angle to the length of the hypotenuse, which is $\frac{\sqrt{3}}{2}$.
Conclusion
In conclusion, the input and output values for determining the sine of $60^\circ}$ are the angle $60^{\circ}$ and the ratio of the length of the side opposite the angle to the length of the hypotenuse, respectively. The correct option is B$; Output $\frac{\sqrt{3}}{2}$.
Common Mistakes to Avoid
When determining the sine of an angle, it is essential to avoid common mistakes. Some common mistakes include:
- Confusing the input and output values
- Not using the correct ratio of the length of the side opposite the angle to the length of the hypotenuse
- Not considering the angle in the correct quadrant
Real-World Applications
The sine function has numerous real-world applications, including:
- Navigation: The sine function is used in navigation to calculate distances and directions.
- Physics: The sine function is used in physics to describe the motion of objects.
- Engineering: The sine function is used in engineering to design and analyze structures.
Final Thoughts
In conclusion, the input and output values for determining the sine of $60^\circ}$ are the angle $60^{\circ}$ and the ratio of the length of the side opposite the angle to the length of the hypotenuse, respectively. The correct option is B$; Output $\frac{\sqrt{3}}{2}$. By understanding the sine function and its applications, we can better navigate the world around us.
