Mathieu function

Definition(s)

In mathematics, Mathieu functions, sometimes called angular Mathieu functions, are solutions of Mathieu's differential equation

${\\displaystyle {\ rac {d^{2}y}{dx^{2}}}+(a-2q\\cos(2x))y=0,}$

where $a, q$ are real-valued parameters. Since we may add $π/2$ to $x$ to change the sign of $q$ , it is a usual convention to set $q \geq 0$ .
