Hi Mohan. I wanted to talk to you about this edit that you made to transcendental equation. It looks like you copied a sentence directly from your textbook. This is not allowed on Wikipedia, both because it violates copyright and is plagiarism. Make sure that whatever material you add is in your own words. Also be careful of close paraphrasing, when you only change a copied passage a little to make it look like your own. This is also not allowed. If you have any questions about this, or anything else, let me know.
