Answer 2

Of course, I'd be happy to help you!

The equation you provided is:

cos(π - x) = 1

To solve this equation, we need to find the values of x that satisfy the equation. Remember that the cosine function returns values in the range [-1, 1]. Since cos(π) = -1, cos(π - x) can be 1 only if the angle (π - x) is such that the cosine function evaluates to 1.

For the cosine function to be equal to 1, the angle (π - x) must be a multiple of 2π. In other words:

π - x = 2πn, where n is an integer.

Now, we can solve for x:

x = π - 2πn x = π(1 - 2n)

So, the general solution for x is:

x = π(1 - 2n), where n is an integer.

This means there are infinitely many solutions for x that satisfy the equation cos(π - x) = 1. For any integer value of n, you can plug it into the formula above to find a corresponding value of x that satisfies the equation.
