What will I learn?
This course provides a clear path to understanding injective functions from basics. You will study functions, sets, and logic, learn exact definitions and proofs, test with algebra and calculus, create examples and counterexamples, and apply to equations, linear maps, invertibility, and practical identification systems.

Your classes are perfect. I got the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
