I can help you in solving first and second order differential equations. Questions must be at the Undergraduate level. Do not expect me to do all your homework.. If you have a homework question with no clues on how to go about, I will only give you some pointers on solving them.

Experience in the area

Ph.D. in Mathematics with more than 20 years of teaching.
In addition to undergraduate calculus, I taught many more advanced subjects like Complex Analysis, General Topology, Numerical Analysis, Operations Research, Graph Theory, Mathematical Analysis, Mathematical Economics, Optimisation Theory.

Education/Credentials

Ph.D. (University of Toledo, USA)

What do you like about this subject?

Differential equations have applications in many areas. One can solve many real life problems using methods of differential equations.
