**Transcription for Educational Website:** --- **Trigonometric Expression Simplification** Let \(\sin t = a\), \(\cos t = b\), and \(\tan t = c\). Write the expression in terms of \(a\), \(b\), and \(c\). \[ 5 \sin (-t) - \sin t \] The expression to simplify is: \[ 5 \sin (-t) - \sin t = \boxed{\phantom{answer}} \] *(Simplify your answer.)* *Note:* The sine function is odd, which means \(\sin(-t) = -\sin(t)\). \[ Enter your answer in the answer box. \] *Save for Later* --- There are no graphs or diagrams included in this content.
