Question

ii) The value of tan31° + tan14° + tan31*tan14° ​

Answer 1

Answer:

1

Step-by-step explanation:

we know that tan45 = 1

tan(31+14) = 1

(tan 31 + tan 14) / (1− tan31 tan14) = 1

$tan(x+y) = \frac{tan \: x \: + \: tan \: y}{1 - tan \: x \times tan \: y}$

tan 31 + tan 14 = 1 − tan 31.tan 14.tan 31 + tan 14 + tan 31.tan 14 = 1
