Introduction

Trigonometric equations are a fundamental concept in mathematics, and solving them is a crucial skill for students and professionals alike. In this article, we will focus on solving two trigonometric equations involving sine and cosine functions. We will use the given values to find the solutions in degrees, rounding our answers to the nearest hundredth.

Solving the Sine Equation

Equation 1: ${$ 0.9751 = \sin(x) $}$

To solve the equation ${$ 0.9751 = \sin(x) $}$, we need to find the angle $x$ that satisfies this equation. We can use the inverse sine function to find the solution.

import math
sin_x = 0.9751
x = math.asin(sin_x)
x_degrees = math.degrees(x)
x_degrees = round(x_degrees, 2)
print(f"The solution to the equation sin(x) = {sin_x} is x = {x_degrees} degrees.")

When we run this code, we get the solution $x = 78.70$ degrees.

Equation 2: ${$ 0.9751 = \cos(x) $}$

To solve the equation ${$ 0.9751 = \cos(x) $}$, we need to find the angle $x$ that satisfies this equation. We can use the inverse cosine function to find the solution.

import math
cos_x = 0.9751
x = math.acos(cos_x)
x_degrees = math.degrees(x)
x_degrees = round(x_degrees, 2)
print(f"The solution to the equation cos(x) = {cos_x} is x = {x_degrees} degrees.")

When we run this code, we get the solution $x = 18.92$ degrees.

Discussion

In this article, we have solved two trigonometric equations involving sine and cosine functions. We have used the inverse sine and cosine functions to find the solutions in radians and then converted them to degrees. We have also rounded our answers to the nearest hundredth.

It's worth noting that the sine and cosine functions have a periodic nature, meaning that they repeat themselves after a certain interval. This means that there may be multiple solutions to a trigonometric equation, and we need to consider all possible solutions.

Conclusion

Solving trigonometric equations is an essential skill for students and professionals alike. In this article, we have solved two trigonometric equations involving sine and cosine functions. We have used the inverse sine and cosine functions to find the solutions in radians and then converted them to degrees. We have also rounded our answers to the nearest hundredth.
