Introduction

In mathematics, the conversion between radians and degrees is a fundamental concept that is essential for solving problems in trigonometry, calculus, and other areas of mathematics. Radians and degrees are two different units of measurement for angles, and understanding the relationship between them is crucial for accurate calculations. In this article, we will explore the conversion of $\frac{7 \pi}{4}$ radians to degrees, and provide a step-by-step guide on how to perform this conversion.

Understanding Radians and Degrees

Radians and degrees are two different units of measurement for angles. Radians are a unit of measurement that is based on the ratio of the arc length to the radius of a circle, while degrees are a unit of measurement that is based on a 360-degree circle. To convert between radians and degrees, we need to understand the relationship between these two units.

The Relationship Between Radians and Degrees

The relationship between radians and degrees is based on the fact that a full circle is equal to $2 \pi$ radians and 360 degrees. This means that we can convert between radians and degrees by using the following conversion factor:

$$1 \text{ radian} = \frac{180}{\pi} \text{ degrees}$$

Converting $\frac{7 \pi}{4}$ Radians to Degrees

To convert $\frac{7 \pi}{4}$ radians to degrees, we can use the conversion factor above. We can start by multiplying $\frac{7 \pi}{4}$ by the conversion factor:

$$\frac{7 \pi}{4} \times \frac{180}{\pi} = \frac{7 \pi}{4} \times \frac{180}{\pi}$$

Simplifying the Expression

To simplify the expression, we can cancel out the $\pi$ terms:

$$\frac{7 \pi}{4} \times \frac{180}{\pi} = \frac{7 \times 180}{4}$$

Evaluating the Expression

To evaluate the expression, we can multiply 7 by 180 and then divide by 4:

$$\frac{7 \times 180}{4} = \frac{1260}{4}$$

Simplifying the Fraction

To simplify the fraction, we can divide 1260 by 4:

$$\frac{1260}{4} = 315$$

Conclusion

In conclusion, $\frac{7 \pi}{4}$ radians is equivalent to 315 degrees. This conversion is based on the relationship between radians and degrees, and can be performed using the conversion factor above. Understanding the conversion between radians and degrees is essential for solving problems in trigonometry, calculus, and other areas of mathematics.
