x in (-oo:+oo)
Y = (300-(2*x))/3.141592654 // - (300-(2*x))/3.141592654
Y-((300-(2*x))/3.141592654) = 0
Y-0.31830989*(300-2*x) = 0
Y-0.31830989*(300-2*x) = 0
Y+0.63661978*x-95.492967 = 0
Y+0.63661978*x-95.492967 = 0
Y+0.63661978*x-95.492967 = 0 // - Y-95.492967
0.63661978*x = -(Y-95.492967) // : 0.63661978
x = (-(Y-95.492967))/0.63661978
x = 1.57079631*(95.492967-Y)
x = 1.57079631*(95.492967-Y)
