Xcos Ω / A + ysin Ω / b = 1, xsin Ω / a-ycos Ω / b = 1

Xcos Ω / A + ysin Ω / b = 1, xsin Ω / a-ycos Ω / b = 1

Xcos Ω / A + ysin Ω / b = 1, (xcos Ω / A + ysin Ω / b) ^ 2 = 1, that is, (xcos Ω / a) ^ 2 + 2 * xcos Ω / A * ysin Ω / B + (ysin Ω / b) ^ 2 = 1, xsin Ω / a-ycos Ω / b = 1 (xcos Ω / a-ysin Ω / b) ^ 2 = 1, that is, (xcos Ω / a) ^ 2-2 * xcos Ω / A * ysin Ω / B + (ysin Ω / b) ^ 2 = 1
