| After running the code, only all the sections resulting from the code execution are extracted. How can I modify it to select all other content except the code itself—such as manually entered text, inserted images, and other complete content? |
| This achieves the desired result. Thank you! |
| Although the obtained result does not contain secant terms, its form is not what I wanted. The desired form is as shown in the image in the original post. ![enter image description here][1] [1]:... |
