Solution for sin(5)=400/x equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

sin(5) = 400/x // - 400/x

sin(5)-(400/x) = 0

sin(5)-400*x^-1 = 0

-400*x^-1 = -sin(5) // : -400

x^-1 = sin(5)/400

-1 < 0

1/(x^1) = sin(5)/400 // * x^1

1 = (sin(5)/400)*x^1 // : sin(5)/400

400*(sin(5))^-1 = x^1

x = 400*(sin(5))^-1

x = 400*(sin(5))^-1
