SUMMARY

The equation sin y = .814 - 7.718 * sin x is solved to yield y = 24.079 (sin(1.751x) - .138) + 17.711. The solution involves taking the inverse sine of both sides, resulting in y = sin^(-1)(.814 - 7.718 * sin(x)). The provided solution diverges from the graph of the derived function, prompting inquiries about the validity of the stated solution.

The Attempt at a Solution



I know the answer to the solution is y = 24.079 (sin1.751x - .138) + 17.711

I do not know the work to get here though...

Well, the obvious thing to do is take the inverse sine of both sides.
That would give you sin^(-1)(sin (y)) = sin^(-1)(.814 - 7.718*sin(x))

IOW, y = sin^(-1)(.814 - 7.718*sin(x))

The graph of this function is nothing like the graph of what you gave as the solution, so I would have to ask you why it is that you know that y = 24.079 (sin1.751x - .138) + 17.711 is the solution.
