**Python/Sympy trigonometric solution of cubic equation**

Let's restrict the domain so the function is one-to-one on the restricted domain while preserving the original range. The graph of the sine function is one-to-one on the interval If we restrict the domain of the sine function to that interval , we can take the arcsine of both sides of each equation.... Let's restrict the domain so the function is one-to-one on the restricted domain while preserving the original range. The tangent function is one-to-one on the interval If we restrict the domain of the tangent function to that interval , we can take the arctangent of both sides of the equation and isolate the x.
