Limit sin(x)/x = 1 - MIT OpenCourseWare | Free Online Course Materials 在中部非洲的赤道密林中世世代代生活著一群身材矮小的居民,他們自稱是“森林之子”,奉這片原始森林為其生身父母和至高之神,他們就是俾格米人。 俾格米人是中非地區最早的居民,是史前桑加文明的繼承人。今天在剛果(金)、剛果(布)、中非共和國、布隆迪、盧旺達、烏干達等國的密林中都有分sin(x) lim = 1 x→0 x In order to compute specific formulas for the derivatives of sin(x) and cos(x), we needed to understand the behavior of sin(x)/x near x = 0 (property B). In his lecture, Professor Jerison uses the definition of sin(θ) as the y-coordinat...
