Q. Express as a function of a DIFFERENT angle, 0θ<360 0^{\circ} \leq \theta<360^{\circ} .\newlinecos(74) \cos \left(74^{\circ}\right) \newlinecos() \cos \left(\square^{\circ}\right)
  1. Understand Co-function Identities: Understand the concept of co-function identities. Co-function identities relate the trigonometric functions of an angle to the trigonometric functions of its complement. The complement of an angle θ\theta is (90°θ)(90° - \theta). For cosine, the co-function identity is cos(θ)=sin(90°θ)\cos(\theta) = \sin(90° - \theta).
  2. Apply Co-function Identity: Apply the co-function identity to cos(74)\cos(74^\circ). Using the co-function identity, we can express cos(74)\cos(74^\circ) as sin(9074)\sin(90^\circ - 74^\circ).
  3. Calculate Complement: Calculate the complement of 74°74°. The complement of 74°74° is 90°74°=16°90° - 74° = 16°.
  4. Write Final Expression: Write the final expression.\newlineTherefore, cos(74°)\cos(74°) can be expressed as sin(16°)\sin(16°).
