Multiple Choice

Find the relative minima of $f ( x ) = \cos ^ { 2 } ( 9 x ) \text { on the interval } ( 0,1.396 ) \text { by applying }$ the First Derivative Test. Round numerical values in your answer to three decimal places.

A) relative minima: $( 0.175,0 ) ( 0.349,0 ) , ( 0.698,0 )$
B) relative minima: $( 0.175,0 ) , ( 0.524,0 ) , ( 0.873,0 ) , ( 1.222,0 )$
C) relative minima: $( 0.698,0 ) , ( 0.873,0 ) , ( 1.222,0 ) , ( 0.524,0 )$
D) relative minima: $( 0.349,1 ) , ( 0.698,1 ) , ( 1.047,1 )$
E) relative minima: $( 0.349,1 ) , ( 0.698,0 ) , ( 1.047,0 )$
