Question

3 tg 2.3 * ctg 2.3 =? 

Answer 1

$tg \alpha *ctg \alpha =1\\\\3tg2,3*ctg2,3=3*1=3$

Answer 2

We can begin by using the identities:

tg(x) = sin(x) / cos(x)

ctg(x) = cos(x) / sin(x)

Substituting these identities, we get:

3 tg(2.3) * ctg(2.3) = 3 [sin(2.3) / cos(2.3)] [cos(2.3) / sin(2.3)]

= 3 * sin(2.3) * cos(2.3) / (cos(2.3) * sin(2.3))

= 3

Therefore, 3 tg(2.3) * ctg(2.3) = 3.
