Question

cot 102 degree - cot 168 degree = ? with explainatio ​

Answer 1

Step-by-step explanation:

cot 102=cot(90+12)=-tan12 because cot(90+x) =-tanx

cot 168=cot(180-12) =-cot 12 because cot(180-x) =-cotx

so cot102-cot168=-tan12-(-cot12)

-tan12+cot12=cot12-tan12

THEREFORE YOUR ANSWER IS Cot12-tan12

I hope you are satisfied by my answer
