Problem Let f ( x ) = ( cos ( 5 x 2 ) ) 3 f(x)=\bigl(\cos(5x^{2})\bigr)^{3} f ( x ) = ( cos ( 5 x 2 ) ) 3 . Determine f ′ ( x ) f'(x) f ′ ( x ) .
(a) − 10 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 ) -10x\,(\cos(5x^{2}))^{2}\sin(5x^{2}) − 10 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 )
(b) − 30 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 ) -30x\,(\cos(5x^{2}))^{2}\sin(5x^{2}) − 30 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 )
(c) 30 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 ) 30x\,(\cos(5x^{2}))^{2}\sin(5x^{2}) 30 x ( cos ( 5 x 2 ) ) 2 sin ( 5 x 2 )
(d) − 30 x cos ( 5 x 2 ) sin ( 5 x 2 ) -30x\,\cos(5x^{2})\sin(5x^{2}) − 30 x cos ( 5 x 2 ) sin ( 5 x 2 )
