  • Góc tà hành là góc không đổi giữa đường đi và các kinh tuyến. (The loxodromic angle is the constant angle between the path and the meridians.)

Advanced Usage

• "đường tà hành": loxodromic curve, loxodromic line. This is the full, more common term for the concept.
  • Việc tính toán đường tà hành rất quan trọng trong hàng hải cổ điển. (Calculating the loxodromic line was very important in classical navigation.)
