Penjelasan dengan langkah-langkah:

1. sin 30° - tan 45° - cos 60°

  • = 1/2 - 1 - 1/2
  • = 1/2 - 1/2 - 1
  • = -1

2. sin 90° + cos 90°

  • = 1 + 0
  • = 1

3. tan 45° - cos 60°

  • = 1 - 1/2
  • = 1/1 - 1/2
  • = 2/2 - 1/2
  • = 1/2

4. sin 60° + cos 30° - tan 30°

  • = √3/2 + √3/2 - √3/3
  • = 3√3/6 + 3√3/6 - 2√3/6
  • = 3√3 + 3√3 - 2√3 / 6
  • = 4√3/6
