Since the sin ranges from -1 to +1,
3 sin ranges from -3 to +3.

You can put this solution on YOUR website! The expression 3 sin 1/2x reaches its maximum value when x, expressed in radians, equals
pi radians. The max value is +3.
Pi is the principal solution. The max of +3 occurs at
x = pi + n*4pi, n = 0,1,2,3,...

Not pie, the dessert, pi, the Greek letter.
