Is the differential equation solvable?

Click For Summary
SUMMARY

The differential equation dy/dx = tan(x^2) presents a challenge due to the non-existence of an elementary function for its solution. To find the steady state solution, one must identify the equilibrium solution, which is defined as a constant function where dx/dt = 0. This leads to solving the equation tan(x^2) = 0, acknowledging that the periodic nature of the tangent function results in multiple solutions.

Here is the question. Find the steady state solution of the differential equation below.

dy/dx = tan(x^2)

What makes this one difficult is that the tangent has no elementary function.

Can anyone explain how to find the steady state solution? Thanks.

The problem does not ask you to solve the equation. An "equilibrium" solution, or "steady state" solution for a problem like this is a constant function. That means that dx/dt= 0. So you only have to solve tan(x^2)= 0. Of course, because tangent is a periodic function, there will be many solutions to that.
