Answer 2

It seems like you're trying to solve equations involving the sine function. Let's break down your equations:

1. sin(a) = 0

2. sin(a) = 0.5

3. sin(a) = -1

4. For the equation sin(a) = 0, this means that the sine of angle 'a' is equal to 0. In trigonometry, the sine function equals 0 at certain angles. The solutions for this equation are any angle 'a' where sin(a) = 0. These angles occur at multiples of pi (π), so the solutions can be written as:

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

   In other words, 'a' can be any integer multiple of pi.

5. For the equation sin(a) = 0.5, you are looking for angles 'a' where the sine function equals 0.5. The most common solution to this equation is:

   a = π/6 + 2nπ, where n is an integer (..., -2, -1, 0, 1, 2, ...)

   This solution corresponds to the angle in the unit circle where the sine value is 0.5, which is π/6 radians (30 degrees), and then you can add multiples of 2π (full circles) to get other solutions.

6. For the equation sin(a) = -1, you are looking for angles 'a' where the sine function equals -1. There is one common solution to this equation:

   a = -π/2 + 2nπ, where n is an integer (..., -2, -1, 0, 1, 2, ...)

   This solution corresponds to the angle in the unit circle where the sine value is -1, which is -π/2 radians (-90 degrees), and then you can add multiples of 2π (full circles) to get other solutions.

So, those are the solutions to the three equations you provided involving the sine function.
