Question

Cos x/8=0,какое решение??

Answer 1

$cos \: \frac{x}{8} = 0$

$\frac{x}{8} = arccos(0)$

$x = 8 \frac{\pi}{2}$

$x = 4\pi$

Answer 2

To find the solution to the equation cos(x)/8 = 0, we need to solve for x.

To do this, we need to remember that when the fraction is equal to zero, the numerator (cos(x)) must be equal to zero, and the denominator (8) cannot be zero since division by zero is undefined.

So, to find the solution, we set cos(x) = 0 and solve for x:

cos(x) = 0

Now, let's recall the values of the cosine function:

cos(0) = 1 cos(pi/2) = 0 cos(pi) = -1 cos(3pi/2) = 0 cos(2pi) = 1 cos(5pi/2) = 0 ... and so on.

Since cosine is a periodic function, it repeats every 2π radians.

The solutions for x are the angles for which cos(x) = 0:

x = π/2 + 2πn x = 3π/2 + 2πn

where n is an integer (..., -2, -1, 0, 1, 2, ...).

These are the solutions for the given equation cos(x)/8 = 0.
