It is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram, Matita and NuPRL. Agda is a dependently typed functional programming language. It has inductive families, i.e., data types which depend on values, such as the type of vectors of a given length. It also has parametrised modules, mixfix operators, Unicode characters, and an interactive Emacs interface which can assist the programmer in writing the program. </p> <p><a href="http://coq.inria.fr/"> The Coq Proof Assistant </a> &nbsp; Coq is a formal proof management system. It provides a formal language to write mathematical definitions, executable algorithms and theorems together with an environment for semi-interactive development of machine-checked proofs. Typical applications include the formalization of programming languages semantics, the formalization of mathematics, and teaching. </p> <p><a href="http://zimmer.csufresno.edu/~larryc/proofs/proofs.html"> How to Write Proofs </a> &nbsp; California State University, Fresno </p> <p><a href="http://www.pancakemath.org/letssay/LetsSay.htm#Contents"> Let's Say: A Child's First Calculus </a> &nbsp; A set of traps, carefully laid out for early success in doing axiomatic proofs.
