Question

4.ctgx = 0помогите решить ​

Answer 1

Ответ:

90°

Пошаговое объяснение:

Ctg 90°=0 (за таблицею котангенсів), тому х=90°.

Answer 2

To solve the equation ctgx = 0, we need to find the values of x that satisfy this equation.

The function ctgx is the reciprocal of the tangent function, also known as the cotangent function. The cotangent of an angle is defined as the ratio of the adjacent side to the opposite side in a right triangle.

In this case, ctgx = 0 means that the cotangent of x is equal to 0. The cotangent is 0 when the tangent is undefined, which occurs at multiples of π (pi).

So, the solutions to the equation ctgx = 0 are given by:

x = π * n

where n is an integer. In other words, x can take on any value that is a multiple of π.

For example, some possible solutions are:

• x = 0
• x = π
• x = 2π
• x = -π
• x = -2π

And so on.

Please note that these are just a few examples, and there are infinitely many solutions to this equation.
