Question

Чему равен tg 180° И почему?

Answer 1

Tg180 равен 0, так как тангенс это синус делить на косинус, синус в 180 равен 0

Answer 2

Tangent of 180°

The tangent of 180° is undefined.

The tangent function is defined as the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle in a right triangle. However, in a right triangle with an angle of 180°, the side adjacent to the angle is zero, resulting in division by zero. Division by zero is undefined in mathematics.

Therefore, the tangent of 180° does not have a numerical value.
