Question

Найдите tga если ctg a =2

Answer 1

$tga= \frac{1}{ctga} = \frac{1}{2}$

Answer 2

Tg a =1/ctga=1/2=0.5

Answer 3

Solving for ctg a when tg a = 2

To solve for ctg a when tg a = 2, we can use the relationship between tg a and ctg a. The formula for ctg a in terms of tg a is:

ctg(2x) = 1 / tg(2x)

Given that tg a = 2, we can substitute this value into the formula to find ctg a.

Using the formula: ctg a = 1 / tg a

Substituting the value of tg a: ctg a = 1 / 2

Therefore, ctg a = 1/2.

This calculation is based on the relationship between tg a and ctg a, and the substitution of the given value of tg a into the formula.
