Find all trigonometric ratios for 180 degrees

We have to find the trignometric ratios of all angles of 180 degress

180 degrees

Given below is the value of 180º for all the trigonometric ratios

  • sin 180° = sin (2 × 90° – 0°) = sin 0° = 0
  • cos 180° = cos (2 × 90° – 0°) = – cos 0° = – 1
  • tan 180° = tan (2 × 90° + 0°) = tan 0° = 0
  • csc 180° = csc (2 × 90° – 0°) = csc 0° = Undefined
  • sec 180° = sec (2 × 90° – 0°) = – sec 0° = – 1
  • cot 180° = cot (2 × 90° + 0°) = cot 0° = Undefined
