sin cos formula

Deriving Euler’s Formula: e^ix = cos(x) + i sin(x) (VIDEO!) : Thinking Mathematics! 隨著社會風氣的開放,許多的觀念也都開始出現了轉變,很多事情已經不能再用傳統的思維來看待跟探討,其中最大的變化非「性觀念」莫屬。古早的社會中,「性」不要說談論了,根本是完全不可以碰觸的禁忌話題,連稍微穿得暴露一點都會被認定離經叛道,更別說發生萬一發生「婚前性行為」,那女孩子可能會被認為不守婦道,男孩Deriving Euler’s Formula: e^ix = cos(x) + i sin(x) (VIDEO!) Perhaps the most surprising and beautiful result in all of mathematics, Euler’s formula, e^ix = cos(x) + i sin(x), turns the theory of trigonometry into a simple study of exponents. (And put in x...
