I'm kind of stuck on the final steps of this problem.
Determine all solution of the equation 5 sin 3x - 11= 3 sin 3x - 12 in the domain 0≤x≤2π
I've gotten to the point of sin 3x = -0.5, but I'm not sure of what to do next.
Hello, DemonX01!
A variation of skeeter's solution . . .
You have: .Determine all solutions of the equation: . . in the domain
I've gotten to the point of sin 3x = -0.5,
but I'm not sure of what to do next.
You should know that: . . . . plus its variations.
. . So: .
Therefore: .
