Question

Уравнение sin 3x= -2,3

Answer 1

sin(3x)= -2,3

sin(3x)= -23/10

x∉R, т.к. sin(3x)∈[-1,1]

Answer 2

The equation you've provided is:

sin(3x) = -2.3

However, there seems to be a mistake because the value of the sine function is always between -1 and 1. It cannot be -2.3 or any value beyond that range.

Please double-check the equation you want to solve or provide more context, and I'd be happy to help you further.
