bsc 1st year maths trigonometry formulae
tools for simplifying expressions and solving equations: Pythagorean Identities sin² θ + cos² θ = 1 1 + tan² θ = sec² θ 1 + cot² θ = csc² θ Quotient Identities tan θ = sin θ / cos θ cot θ = cos θ / sin θ Reciprocal Identities csc θ = 1 / sin θ sec θ = 1 / cos θ Important
