Question

If x=15 evaluate 8 sin2x cos4x sin6x

Answer 1

Answer:

Step-by-step explanation:

8 sin2x cos4x sin6x

= 8 sin(2*15) cos(4*15) sin(6*15)

= 8 sin30 cos60 sin 90

= 8 * (1/2) * (1/2) * 1

= 2

Answer 2

Answer:

2

Step-by-step explanation:

8 sin2x cos4x sin6x

8 sin2x cos4x sin6x= 8 sin(2*15) cos(4*15) sin(6*15)

8 sin2x cos4x sin6x= 8 sin(2*15) cos(4*15) sin(6*15)= 8 sin30 cos60 sin 90

8 sin2x cos4x sin6x= 8 sin(2*15) cos(4*15) sin(6*15)= 8 sin30 cos60 sin 90= 8 * (1/2) * (1/2) * 1

8 sin2x cos4x sin6x= 8 sin(2*15) cos(4*15) sin(6*15)= 8 sin30 cos60 sin 90= 8 * (1/2) * (1/2) * 1= 2
