94 - 10 cos (\frac{π}{12} (x - 9.3))

94 + 7.60405 \dots cos (0.26179 \dots x) - 6.49448 \dots sin (0.26179 \dots x)

解答ステップ

94 - 10 cos (\frac{π}{12} (x - 9.3))

10 cos (\frac{π}{12} (x - 9.3)) = 10 (- 0.7604059656 cos (0.26179 \dots x) + 0.64944 \dots sin (0.26179 \dots x))

= 94 - 10 (0.64944 \dots sin (0.26179 \dots x) - 0.7604059656 cos (0.26179 \dots x))
