Find the exact value.sin

Rank the following atomic models for hydrogen from the earliest (simple) to the latest (most complex) as our understanding of the atom and its structure developed.

Use fundamental trigonometric identities to find the values of the functions.Given sec θ = for θ in Quadrant IV, find csc θ and cos θ.

Atomic and molecular spectra are:
