Find x where sin(x) gives the same result when expressed in radians or degrees.

[TheAgileWarrior249]

What I tried:The answer is not 0.f(x) represents degrees and g(x) represents radians.f(x) = g(x)What would I have to do next?BONUS: How could this value of x be found using a graph?​

The main difficulty here is to define what you mean by "f(x) represents degrees", and so on.

I would define

f(x) = sin(x degrees converted to radians)
g(x) = sin(x)

where sin is the usual sine taking radians. (Our f could be called sind or sin_d.)

Write out what f(x) really is, and then write your equation and solve it for x.

You may find it helpful to sketch a graph before trying to solve the equation, in order to see what you will have to do.

For more help, please show your work, so we can see what hints you need, and what you already understand. This problem requires a little twisting of your mind, and I don't want to twist it in the wrong direction.
