Example 12 - Prove that (sin - cos θ + 1)/(sin + cos - 1)

Prove that 1/(sin θ + cos θ) + 1/(sin θ - cos θ) = 2 sin θ/(1 – 2

Use small-angle approximations (sin θ≈θ and cos θ≈1) to

If sec θ + tan θ = p, prove that sin θ = (p2 – 1)/ (p2 + 1) - Noon

Example 12 - Prove that (sin - cos θ + 1)/(sin + cos - 1)
