Question

Cos(x-)=-1​

Answer 1

Ответ:

x=$\frac{3\pi }{2}$+2$\pi$n, n∈Z

Пошаговое объяснение:

cos(x-$\frac{\pi }{2}$)=-1​

x-$\frac{\pi }{2}$=$\pi$+2$\pi$n, n∈Z

x=$\frac{\pi }{2}$+$\pi$+2$\pi$n, n∈Z

x=$\frac{3\pi }{2}$+2$\pi$n, n∈Z

Answer 2

It seems like you have an equation involving the cosine function:

cos(x) = -1

To solve this equation, you need to find the values of x that satisfy it. The cosine function has a range between -1 and 1, and it is equal to -1 at specific angles. In this case, cos(x) is equal to -1 when x is an odd multiple of pi (π) radians.

So, the solutions to the equation cos(x) = -1 are given by:

x = π + 2nπ, where n is an integer

In other words, x can take on any value of the form π + 2nπ, where n is an integer (e.g., n = 0, 1, -1, 2, -2, ...). These values represent the angles in radians for which the cosine function is equal to -1.
