Question

1)sin x = -1 2)0.5tg x = 0

Answer 1

1)sin 270=-1=> x= 270 градусов
2) tg x=0/0,5=0=> x=0 градусов или 180 градусов или 360 градусов

Answer 2

To solve the equations you've provided:

1. sin(x) = -1: The sine function takes values between -1 and 1. If sin(x) = -1, then x must be an angle for which the sine function is at its minimum value of -1. This occurs at 270 degrees (or 3π/2 radians). So, x = 270 degrees or x = 3π/2 radians.

2. 0.5tan(x) = 0: To solve for x in this equation, we can start by isolating tan(x):

   0.5tan(x) = 0

   Now, divide both sides by 0.5:

   tan(x) = 0

   To find the values of x for which tan(x) is equal to 0, you need to consider the unit circle or the graph of the tangent function. Tangent is equal to 0 at multiples of π (or 180 degrees). So, x can be expressed as:

   x = nπ, where n is an integer.

   This means x can be any integer multiple of π (180 degrees).
