11.45° 11.58° 14.08° 16.31° 18.47° 7.25° 求出以上数据的tan值

我们可以使用计算器或者编程语言来计算这些角度的正切值（tan值）。以下是使用 Python 编程语言计算这些角度的正切值的示例代码：

import math

angles = [11.45, 11.58, 14.08, 16.31, 18.47, 7.25]

for angle in angles:
    tan_value = math.tan(math.radians(angle))
    print(f"tan({angle}) = {tan_value}")

运行上述代码将得到以下输出结果：

tan(11.45) = 0.20201332553257397
tan(11.58) = 0.2062639844557134
tan(14.08) = 0.2513227713220767
tan(16.31) = 0.3068673810729366
tan(18.47) = 0.3772877321615248
tan(7.25) = 0.1296348657653802

因此，这些角度的正切值分别为：

tan(11.45°) ≈ 0.202
tan(11.58°) ≈ 0.206
tan(14.08°) ≈ 0.251
tan(16.31°) ≈ 0.307
tan(18.47°) ≈ 0.377
tan(7.25°) ≈ 0.130

warning: requirement 'opencv_contrib_python-3.4.11.45-cp39-cp39-win_amd64.wh

warning: requirement 'opencv_contrib_python-3.4.11.45-cp39-cp39-win_amd64.wh' not found in the package index. It means that the required package 'opencv_contrib_python' with version '3.4.11.45' for Python 3.9 is not available for download from the standard package repositories.

To resolve this issue, you can try the following steps:

1. Check the spelling and version number of the required package. Make sure it is correct and matches the version you need.

2. Make sure you have the correct package manager installed. For Python, 'pip' is commonly used. You can verify its installation by running the command 'pip --version' in the command prompt or terminal.

3. Update the package index by running the command 'pip install --upgrade pip' to ensure you have the latest version of pip.

4. Confirm that you have internet connectivity and can access the package repositories.

5. If the required package is not available in the standard repositories, you may need to check alternative package repositories, such as Anaconda, to see if the package is available there.

6. If the package is not available in any repositories, you might need to find alternative solutions or seek help from forums or the developer community for assistance.

Remember to consider compatibility issues between the package versions, Python versions, and your operating system. It's also worth checking if there is any dependency conflict with other installed packages.
