New method / kaedah baru / 新方式 :

First, find the angle of reflection for bearing in.
Mula-mula dapatkan sudut refleksi bagi bearing masuk.
まず、軸受での反射の角度を見つけます。

• The calculation of angle made ​​by obtaining the smallest angle.
  最小の角度を求めるとのなす角度を算出。
  Pengiraan sudut dibuat dengan mendapatkan nilai sudut terkecil.

 
h1 = 60°; (bearing in)
h2 = -50°; (bearing out)

• get reflection angle for h1
  h1のための反射角を得る。
  dapatkan sudut refleksi bagi h1.

h1a = h1° < 0°? h1° + 180° (value if true) : h1° -180° (value if false);
h1a = 60° < 0°? 60° + 180° : 60° -180° ;
h1a = 60° > 0°? 60° -180° ;
h1a = -120° ; (reflection angle for h1)

• Get intersection angle, x°.
  交差角度、X°を入手してください。
  dapatkan sudut persilangan x°

intersection angle = Math.min((h1a - h2) < 0 ? h1a - h2 + 360 : h1a - h2, (h2 - h1a) < 0 ? h2 - h1a + 360 : h2 - h1a);
intersection angle = Math.min((-120° + 50°) < 0° ? -120° +50° + 360° : -120° +50°, (-50° + 120°) < 0° ? -50° + 120° + 360° : -50° +120°);
intersection angle = Math.min(-70° < 0° ? 290°, 70° < 0° ? 70°);
intersection angle = Math.min(290°, 70°); (get minimum value)
intersection angle = 70°;

direction of deflection / arah pesongan / 偏向方向

negative deflection (- ve) or to the left : h2° between h1a° to 0° AND 0° to h1° positive deflection (+ ve) or to the right : h2° between h1a° to -180° AND h1° to 180°	左または負のたわみ（-VE）： h2° : h1a° ~ 0°, 0° ~ h1°. 右または正たわみ（+ VE）： h2° : h1a° ~ -180°, h1° ~ 180°.
pesongan negatif (-ve ) atau ke kiri : h2° antara h1a° ke 0° DAN 0° ke h1° pesongan positif (+ve ) atau ke kanan : h2° antara h1a° ke -180° DAN h1° ke 180°
