solve the equation: 2 sin(3x) = -1
[Put each step on a separate line - you may use radians or degrees for x, as long as you use the proper symbols] Each intersection between the two lines you graphed was a solution. Write down an expression for all the solutions. Use the variable "n" in place of an integer that, when you change it, gives you a new solution.

Answer:

Step-by-step explanation:

2sin(3x)=-1

3x=invsin(-1/2)

what angle gives 1/2, 30 deg or pi/6

So formal solution is pi/6 but there is another on the other side, at 7pi/6

The 2 basic solutions are: 11pi/18 and 7pi/18

So the expressions are

(11pi/18+2npi/3)

and (7pi/18+2npi/3)
