Question

COS X/2=0 HELP!!!!!! PLEASE!!!

Answer 1

COS X/2=0

x/2=pi/2+2*pi*n, n є Z

x=pi+4*pi*n , n є Z

ответ:   pi+4*pi*n , n є Z

Answer 2

To solve the equation cos(x/2) = 0, we need to find the values of x that satisfy this equation.

From the given equation, we can see that the cosine of x/2 is equal to 0. In trigonometry, the cosine function is equal to 0 at certain angles. These angles are the solutions to the equation.

To find the solutions, we can use the fact that the cosine function is equal to 0 at multiples of π/2. Therefore, we can write the equation as:

x/2 = (2n + 1)π/2, where n is an integer.

To solve for x, we can multiply both sides of the equation by 2:

x = (2n + 1)π, where n is an integer.

This equation gives us the values of x that satisfy the equation cos(x/2) = 0.

Let's find a few solutions:

- When n = 0, x = π/2. - When n = 1, x = 3π/2. - When n = -1, x = -π/2.

These are just a few examples of the infinite number of solutions to the equation.

I hope this helps! Let me know if you have any further questions.
