Question

cot 375 degree in trigonometry ratio​

Answer 1

Step-by-step explanation:

cos-375°

= sin (90° – 375°) = sin -285°

= sin (90° + 375°) = sin 465°

-cos-375°

= cos (180° – 375°) = cos -195°

= cos (180° + 375°) = cos 555°

Note that cos-375° is periodic: cos (-375° + n × 360°) = cos -375 degrees, n.
