Type a math problem

{ \left( \sin ( x ) \right) }^{ 2 } \cdot \left( { \left( \cot ( x ) \right) }^{ 2 } +1 \right)

\cos ( \pi )

\tan ( x )

\cos ( 3x + \pi ) = 0.5

\cot ( x ) \sec ( x ) \sin ( x )

\sin ( \frac { \pi } { 2 } )

\sec ( x )

\sin ( x ) = 1

\tan ( x ) \cdot \left( \csc ( x ) - \sin ( x ) \right)

\tan ( \frac { 4 \pi } { 3 } )
