The amplitude of a sine function is the absolute value of the coefficient of the sine term. In this case, the amplitude is 2.
The period of a sine function is given by the formula 2Ï€ / |b|, where b is the coefficient of the x term. In this case, the period is 2Ï€.
The phase shift of a sine function is given by the formula c / |b|, where c is the constant term in the equation. In this case, the phase shift is π.
