Answer:The cosine function is a mathematical function that takes an angle as input and returns the ratio of the adjacent side length to the hypotenuse length in a right-angled triangle with that angle. The range of the cosine function is always between -1 and 1. Therefore, it is not possible for the cosine of any angle to equal 1.25.
If you are seeing the value of 1.25 for the cosine of an angle, it is likely that there is an error in the calculation or the interpretation of the result. It could also be possible that the value is being rounded off or truncated, leading to a value that is slightly larger than 1.
In any case, if you encounter a value of cosine that is greater than 1 or less than -1, it is a clear indication that there is an error in the calculation or interpretation of the result.

Step-by-step explanation:
The cosine function takes an angle as input and returns the ratio of the adjacent side length to the hypotenuse length in a right-angled triangle with that angle.
The range of the cosine function is always between -1 and 1. This means that the value of cosine for any angle cannot be greater than 1 or less than -1.
If you encounter a value of cosine that is greater than 1 or less than -1, it is a clear indication that there is an error in the calculation or interpretation of the result.
If you see a value of 1.25 for the cosine of an angle, it is not possible as it exceeds the range of the cosine function.
Therefore, if you encounter such a situation, it is likely that there is an error in the calculation or interpretation of the result, and you should double-check your work or seek further clarification.
