The topic of discussion in this article is “Trigonometric Identities”. We can dissect the terminology into two words i.e., “Trigonometric” and “Identities”. Let us look at them individually one by one. The word “Trigonometric” comes from the word Trigonometry (Greek trigonon: triangle and metron: to measure). Therefore, the literal meaning of the word “Trigonometric” is … Read more
