From then on, Rohan became an advocate for using legitimate resources, and he shared his experience with his friends and classmates. He encouraged them to purchase the book or use library resources instead of relying on pirated PDFs.

However, Rohan knew that using a pirated PDF might not be the best option. He decided to purchase the book from a reputable seller, so he could support the author and have a physical copy.

Rohan typed "SD Yadav math book pdf" on Google and started searching. He found a few links, but they seemed suspicious. He then tried searching on Google Drive, hoping to find a shared file or a link to the PDF.

Rohan tried to purchase the book, but it was not available in the local market. He then searched online and found that many websites were selling the book, but at a high price. He didn't want to spend that much money, so he decided to look for a free PDF version.
