SOME BASIC TRIG - KNOW THIS! FUNDAMENTAL TRIG IDENTITIES (IDs)有一老漢是一個典型的莊稼人。他一生中有一個不大但也絕對不小的煩惱，就是他家的木門在開和關的時候都會發出響聲。那響聲又尖銳又乾燥，常令他心煩意亂，全身上下都不舒服。響聲是什麼時候有的，已經無從考證，娶媳婦以前只要忍受自己一個人開關門的尖叫聲就可以了，媳婦進門以後就開始忍受別人製造的聲音。尤為惱火的是，SOME BASIC TRIG - KNOW THIS! FUNDAMENTAL TRIG IDENTITIES (IDs) Memorize these in both “directions” (i.e., left-to-right and right-to-left). Reciprocal Identities cscx = 1 sin x sec x = 1 cosx cot x = 1 tan x sin x = 1 cscx cosx = 1 sec x tan x = 1 cot x ....
