    Study Notes

    Trigonometry Formulas

    • sin² A + cos² A = 1
    • sec² A = 1 + tan² A
    • cosec² A = 1 + cot² A

    Double Angle Formulas

    • sin 2A = 2 sin A cos A
    • cos 2A = cos² A - sin² A
    • cos 2A = 2 cos² A - 1
    • cos 2A = 1 - 2 sin² A
    • tan 2A = 2 tan A / (1 - tan² A)

    Addition and Subtraction Formulas

    • sin(A + B) = sin A cos B + cos A sin B
    • sin(A - B) = sin A cos B - cos A sin B
    • cos(A + B) = cos A cos B - sin A sin B
    • cos(A - B) = cos A cos B + sin A sin B
    • tan(A + B) = (tan A + tan B) / (1 - tan A tan B)
    • tan(A - B) = (tan A - tan B) / (1 + tan A tan B)

    Reciprocal Functions

    • sec θ = 1 / cos θ
    • cosec θ = 1 / sin θ
    • cot θ = 1 / tan θ
    • tan θ = cot(90° - θ)
    • cos θ = sin(90° - θ)

    Half Angle Formulas

    • sin(A/2) = ±√((1 - cos A) / 2)
    • cos(A/2) = ±√((1 + cos A) / 2)

    Other Formulas

    • a cos θ + b sin θ = r cos (θ – α), where r = √(a² + b²) and tan α = b/a
