Question

Simplify cos θ sec θ

Answer 1

\(\large\color{cxxd}{ \rm \cos θ\sec θ=1 }\)
\(\large\color{cxxd}{ \rm \csc θ\sin θ=1 }\)
\(\large\color{cxxd}{ \rm \tan θ\cot θ=1 }\)

Answer 2

\(\normalsize\color{cxxd}{ \rm \cos(- θ)\sec(- θ)= \cos( θ)\sec(- θ) = \cos(-θ)\sec( θ)= \cos( θ)\sec(- θ)=1 }\)

Answer 3

Thank you!!
