\chapter{Trigonometry II} \section{Verifying trig identities}
Check your understanding
Answer True or False: \begin{enumerate} \item To verify a trigonometric identity it is enough to check that it is true for several values of the variable. \item If we find a single value of the variable for which the identity is not true, then we can still try to verify it using algebra and simplification. \item \(\sin\theta +\cos \theta = \sec \theta\) is not an identity. \end{enumerate}
