“对数太难了!”“对数没什么用!!”“高中完全可以不学对数!!!”……这是很多高中生的心声,甚至部分教师也有同感.对数真的没用吗?回顾历史,十六世纪科学技术迅猛发展,尤其天文、测绘等的高速发展,令科学家头痛的巨大繁杂的数字运算,浪费了他们有限的时间,为了减轻人们的计算劳动和提高运算速度,英国数学家纳皮尔,用了20年的时间研究,于1594年掌握了对数的基本原理,给出了对数的性质、定义和应用.对数的发现,为
“” Logarithm no use !! “” High school can not learn logarithms !!! "... This is the voice of many high school students, and even some teachers are feeling the same. Logarithmic really useless? Recalling history, the rapid development of science and technology in the 16th century, especially the rapid development of astronomy, surveying and mapping, etc., so that scientists headache huge and complicated digital computing, a waste of their limited time, in order to reduce people’s calculations Labor and speed of operation, the British mathematician Napier, spent 20 years researching, mastered the basic principle of logarithm in 1594, gave the nature, definition and application of logarithm. The discovery of logarithm was
