Hi there!
My name is Yaicel. I have read your brief and can see that you are looking for a mathematician to solve (step by step with explanation) your DE. As you can see in my profile, I am professionally qualified for this project. That is, I have Nuclear Science degree and actually, PhD studies, with very high level on maths and physics. I have been teaching differential equations for a 6 years to university students. Thus, I would love to help you. Be free to contact me for further specifications.
