Injective Function Course
Gain strong skills in injective functions through proofs, examples, and real applications. Learn to test one-to-one mappings, build counterexamples, and link to linear algebra, invertibility, and uniqueness in maths. Use graphs and logic for advanced problem-solving in various fields.

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, inverses, and practical systems.
