Hello I was trying to solve this sample problem, but I really dont get it.(adsbygoogle = window.adsbygoogle || []).push({});

The book says this word by word:

The equation sin3x=1 implies

3x=(pi/2)+2kpi, k an integer.

x= (pi/6)+(2kpi/3), k an integer *Divide each side by 3.

Because x is not restricted to a finite interval, the given equation has an infinite number of solutions. All the solutions are represented by the equation

x= (pi/6)+2kpi/3

Okay it lost me when it told me 3x=(pi/2)+2kpi.

I am really confused. This is not solved like the rest of the trigonometric equations.
