X y k y x k what is k represented and how y x

+ Sqrt[2 - 2 y] - k)/((y + 1) Sqrt[1 - y^2]), Sqrt[2]/2/m == k/(k - Sqrt[2 - 2 y]), n == Sqrt[2 - 2 Sqrt[1 - m^2]], z == Sqrt[2 - 2 y]/f == Sqrt[(zn)^2 - 2 + 2 y]/ Sqrt[n^2 - f^2], t == (Sqrt[g^2 - 2 g^3 - g^4 + 2 g + 1] + Sqrt[2 - 2 g] - t)/((g + 1) Sqrt[1 - g^2]), Sqrt[2]/2/h == t/(t - Sqrt[2 - 2 g]), q == Sqrt[2 - 2 Sqrt[1 - h^2]], l == Sqrt[2 - 2 g]/p == Sqrt[(lq)^2 - 2 + 2 g]/ Sqrt[q^2 - p^2], (z + 1) x == (l + 1) 2 x == (y + 1) Sqrt[1 - y^2]/ Sqrt[2] == Pi/4, q == m and determine true it or false thank you
