Question

value of tan pi/16/1-tan²pi/16 is​

Answer 1

Sin π

Explanation :-

formula :- 1-tan²A = SecA

so ,

tan π/16 * 16/secπ

= tanπ / secπ = (sinπ/cosπ)/(1/cosπ)

= ( sinπ/cosπ ) * cosπ

= sin π

• Answer is sin π

Answer 2

Answer:

formula :- 1-tan²A = SecA

\begin{gathered} \\ \\ \end{gathered}

\begin{gathered} \\ \\ \end{gathered}

tan π/16 * 16/secπ

\begin{gathered} \\ \end{gathered}

= tanπ / secπ = (sinπ/cosπ)/(1/cosπ)

\begin{gathered} \\ \end{gathered}

= ( sinπ/cosπ ) * cosπ

\begin{gathered} \\ \end{gathered}

= sin π

Answer is sin π
