expand 6.1sin(pi/(18)(x-4.5))-8

expand

6.1 sin (\frac{π}{18} (x - 4.5)) - 8

4.31335 \dots sin (0.17453 \dots x) - 4.31335 \dots cos (0.17453 \dots x) - 8

Solution steps

6.1 sin (\frac{π}{18} (x - 4.5)) - 8

6.1 sin (\frac{π}{18} (x - 4.5)) = 6.1 (0.70710 \dots sin (0.17453 \dots x) - 0.70710 \dots cos (0.17453 \dots x))

= 6.1 (0.70710 \dots sin (0.17453 \dots x) - 0.70710 \dots cos (0.17453 \dots x)) - 8

Expand

6.1 (0.70710 \dots sin (0.17453 \dots x) - 0.70710 \dots cos (0.17453 \dots x)) : 4.31335 \dots sin (0.17453 \dots x) - 4.31335 \dots cos (0.17453 \dots x)

= 4.31335 \dots sin (0.17453 \dots x) - 4.31335 \dots cos (0.17453 \dots x) - 8
