The first six chapters of the textbook of Fundamentals of Complex Analysis (3rd edition) by E.B. Saff and A.D. Snider.
I learned how to solve a variety of differential equations. This is highly useful as a physics major since ODE's are used often, but can be brushed over. However, this class gave me a greater understanding of the math behind the physics problems I complete each week.
Fundamentals of complex analysis. Cauchy Riemann formulas and integrals and applications.
Basic ODEs. Repetitive, computational, but fun. Little crossword puzzles.
I learned about fundamental concepts in Complex Analysis, and I believe that I also improved my mathematical skills more broadly (writing proofs, understanding theorems, etc).
Learned about ODEs and various methods of solving them.
Very complete introduction to complex analysis.
We learned about ordinary differential equations—homogenous, nonhomogenous, and higher-order derivatives. Skills-wise and personally, this course taught me about real-life applications of math because ODE is so prevalent in many fields.
Fundamentals of complex analysis: Complex Derivation and Integration: Cauchy Riemann Equations, Contour Integrals, etc.
I learnt abut first order linear differential equations, separable and autonomous equations, second order homogenous equations, laplace transform and th elike
