Question

Найдите tgA, если : а) ctgA=2; б)ctgA=0,2

Answer 1

Тангенс и котангенс взаимно обратные, поэтому:

а) tgA=$\frac{1}{2}$

b)tgA=$\frac{5}{1}=5$

Answer 2

To find the value of tangent (tg) of angle A, we can use the relationship between tangent and cotangent:

1. For ctgA = 2: The cotangent (ctg) of an angle is the reciprocal of the tangent. So, if ctgA = 2, then tgA = 1/ctgA = 1/2.

2. For ctgA = 0.2: Similarly, if ctgA = 0.2, then tgA = 1/ctgA = 1/0.2 = 5.

So, the values of tangent (tgA) are: a) tgA = 1/2 б) tgA = 5
