The inequality \( \cos(x) \leq 1 \) is true for all real numbers \( x \).
Solución
The inequality \( \cos(x) \leq 1 \) is always true for all real numbers \( x \). The cosine function, which oscillates between -1 and 1, reaches its maximum value of 1 at specific points (e.g., \( x = 2n\pi \) for any integer \( n \)). Therefore, the inequality holds for all \( x \) in the domain of the cosine function.
If you have a specific context or additional conditions related to this inequality, please provide more details!

Did you know that the cosine function is not just a staple in trigonometry, but it also has deep roots in the study of waves and oscillations? From sound waves to light waves, the cosine function helps describe periodic phenomena in nature. Its maximum value of 1 means that, in a wave, that’s the highest point it can reach. When working with inequalities like \( \cos(x) \leq 1 \), it’s essential to remember that cosine oscillates between -1 and 1. A common mistake is to overlook negative values, but with this specific inequality, you won't encounter any issues since the cosine function can never exceed 1. So you can confidently say, for all \( x \), the inequality holds true!
