Recall the identity for the tangent of a negative angle: \(\tan(-t) = -\tan t\).
Substitute the given value \(\tan t = c\) into the expression: \(\tan(-t) - \tan t = -c - c\).
Combine like terms: \(-c - c = -2c\).
Express the final result in terms of \(a\), \(b\), and \(c\). Since the expression only involves \(c\), the answer is \(-2c\).
Thus, the expression \(\tan(-t) - \tan t\) simplifies to \(-2c\) using the given definitions.

Definition of Tangent in Terms of Sine and Cosine

Tangent is defined as the ratio of sine to cosine: tan t = sin t / cos t. Knowing this relationship allows rewriting tangent expressions using sine and cosine values, which is useful when expressing results in terms of a and b.
