(a) List three pairs of trigonometric functions of O and ß that are cofunctions of each other. How are the angles 0 and § related?

Three pairs of trigonometric functions of θ and β that are cofunctions of each other are: Sine and Cosine: sin(θ) = cos(β) Secant and Cosecant: sec(θ) = csc(β) Tangent and Cotangent: tan(θ) = cot(β) The angles θ and β are related in such a way that they are complementary to each other, i.e., their sum is 90 degrees or π/2 radians. This means θ + β = 90° or θ + β = π/2.
