sin(x) = 4
sin⁡(x)=4\sin{\left(x \right)} = 4
Simplify
Detail solution
Given the equation
sin⁡(x)=4\sin{\left(x \right)} = 4
- this is the simplest trigonometric equation
As right part of the equation
modulo =
True

but sin
can no be more than 1 or less than -1
so the solution of the equation d'not exist.

Numerical answer [src] 
x1 = 1.5707963267949 + 2.06343706889556*i
x2 = 1.5707963267949 - 2.06343706889556*i
x2 = 1.5707963267949 - 2.06343706889556*i
