1) Suppose the voltage in a circuit node is approximated as a sinusoid:

v(t) = Vm sin(wt +f)

a)What are the terms Vm, ω, ϕ ? Please draw a picture and explain each term.

b)What is the period T of a sinusoid? Please explain. Derive a formula for the period T of this particular sinusoid.

c)What is the frequency f of a sinusoid? Please explain. Provide a formula for f.

d)What is the relationship between f and ω.
