To express \( \frac{\sec (x)}{\tan (x)} \) in terms of \( \sin (x) \) and \( \cos (x) \), we use the definitions of secant and tangent: \[ \sec(x) = \frac{1}{\cos(x)} \quad \text{and} \quad \tan(x) = \frac{\sin(x)}{\cos(x)}. \] Now, substituting these into the expression gives: \[ \frac{\sec(x)}{\tan(x)} = \frac{\frac{1}{\cos(x)}}{\frac{\sin(x)}{\cos(x)}}. \] When you divide by a fraction, it’s the same as multiplying by its reciprocal: \[ = \frac{1}{\cos(x)} \cdot \frac{\cos(x)}{\sin(x)}. \] Now, the \( \cos(x) \) terms cancel each other out: \[ = \frac{1}{\sin(x)} = \csc(x). \] Thus, simplified, we have: \[ \frac{\sec(x)}{\tan(x)} = \frac{1}{\sin(x)}. \]
