Hello there,
With my distinguished academic background in Mathematics and Economics from a foreign university that I can name (if you wish), and with subsequent experience of 6 years in tutoring students from around the world in Europe, North America, Australia, Middle East, Asia Pacific and elsewhere with great success in numerous undergraduate Mathematics courses, I am very capable of solving these 8 simple DE problems for you very quickly and to your satisfaction.
At $2 per question, the 8 problems should cost you $16, which is the hourly rate I set for my bid. If you wish, I can solve any single one of these 8 problems to prove my experience and familiarity with the topic. Just let me know which problem you want solved, and I can solve that single problem for you, for FREE, to prove my capability.
Let me know what you think.
Regards,
Ami Ostad
