Dear Sir/Madam,
I can help you complete your problems in DEs online, if you kindly relate to me the exact syllabus and some samples of questions to be solved. For your kind information, some modules/courses that I completed include those involving Introductory topics like Discrete Mathematics, Finite Mathematics, Linear Algebra, Calculus (I, II, III), Statistics, Graph Theory, Linear Programming, and more, to more advanced concepts at the Intermediate and Advanced levels, including Differential Geometry, Analysis (Real, Complex), Algebra, Optimization, Topology, Algebraic Geometry, and many more.
Thanks,
Akram Hussein
