Question

what are all trigonomatic identity​

Answer 1

Answer:

The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent. By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse.
