Web11 mei 2024 · I want a list of trig identities with available proofs, not just observations. And they cannot be proven by other trig identities without proofs themselves! For example, we know that: tan x = sin x cos x Well, if we use Soh Cah Toa, then we know that : tan x = O A, cos x = A H, sin x = O H tan x = sin x cos x = O H A H = O A = tan x WebThe six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse cos θ = Adjacent Side/Hypotenuse tan θ = Opposite Side/Adjacent Side sec θ = Hypotenuse/Adjacent Side
