Question

What is the most important trigonometric identity?

Answer 1

Answer:

According to me, there are two most important trigonometric identities - sin and cos.

Step-by-step explanation:

its because these two are the basic building blocks of all the other trigonometrical identities. Like,

tan = sin/cos

cot = cos/sin

cosec = 1/sin

sec = 1/cos

But also, it depends on the question.
