I tried to prove this more mathematically to the best of my ability. Would anyone familiar with writing proofs like to critique this in order for me to improve it and my proof writing? Is this even considered a proof since I guess it could be considered somewhat trivial?(adsbygoogle = window.adsbygoogle || []).push({});

There are so many problems in calculus and physics that ask for proofs. I have not taken any proof writing classes yet. However, I am readingAnalysis4th ed. by Steven Lay in order to introduce me to proofs. Are there any better resources for learning how to write better proofs?

Thanks
