| Abstract: | Giving intuitive proofs of the trigonometric formulas and formulas for the sum of the powers of natural numbers, which are brief, clear and beautiful, this paper attempts to connect the history with the pedagogy of mathematics and to probe into their relation(HPM for brevity). Many historical methods in mathematics, which, more often than not, are intuitive, wonderful and instruc- tive, can greatly interest the students and activate their thinking and creative ability, if they are taught in mathematics classroom. Therefore, the study of HPM is of great significance for the reform of mathematics instruction. |
