Question

tan 15° + tan 75° + cot 15° + cot 15° = ​

Answer 1

Answer:

0.3443401808

Explanation:

tan 15° + tan 75° + cot 15° + cot 15°

=0.3443401808

Answer 2

Step-by-step explanation:

tan 75° + cot 15°= tan (90°-15°) + cot 15°= cot 15° + cot 15°= 2+√3+2+√3= 4+2√3= 2(2+√3)

tan 15°+ cot 15° = 4

tan 15° + tan 75° + cot 15° + cot 15° = 4+ 2(2+√3)
