What does sine actually mean?

why sin(2x)=2sin(x)cos(x)

Derivative of sinx Proof | Differentiation of sinx is cosx Proof

Express the given quantity in terms of sin x and cos x sin 2 X

Where do Sin, Cos and Tan Actually Come From - Origins of Trigonometry - Part 1

Prove TanxSinx + Cosx = Secx

Pre-Calculus Prep: Trig Identity Proof -- 1/sinxcotx = 1/cosx

#Function Sin(x),#Function Cos(x)

sec x - cos x = sin x tan x, verify the identity

cosx / (1 - tan x) + sin x/(1 - cot x) = sin x + cos x
