Amplitude:
Period:
Phase shift:
Explanation:
A wave function of the form

#A# is the amplitude of the wave function. It does not matter if the wave function has a negative sign, amplitude is always positive. 
#\omega# is the angular frequency in radians. 
#theta# is the phase shift of the wave.
All you have to do is identify these three parts and you're almost done! But before that, you need to transform your angular frequency
