How is the following solved?

2. Simple Harmonic Motion is a periodic motion that creates a sinusoidal (sine) wave. The equation for simple harmonic motion can be given as x(t) = Asin wt. The variables x(t) stands for displacement, A stands for amplitude, t stands for time. a. What could w stand for? (Hint: think of the standard formula for a sine wave) b. An object has a frequency of 5/2 oscillations per second, and an amplitude of 6 meters. Write an equation for the displacement of the object, using the given formula for x(t) above. NOTE: W = 2nf, where f is the frequency. x(t) = 2 TT c. Recall that f = -. What does T stand for? An object moves in simple harmonic motion described by x(t) = 3sin2t. What are the Amplitude =_ f= , and T= d. Graph the equation given in part c. (Remember to be in radian mode)
