Write an equation for an alternating current that has a peak amplitude of 36.5 mA, a frequency of 30 Hz, and a phase angle of 63.5o.
Round the numbers in your answer to 3 significant digits:
----
Form:: y = a*sin(b(x+(c/b))+d
amp = |a| = 36.5
freq = (360)/b = 30 implies that b = 12
phase = c/a = 63.5 implies c = 36.5*63.5 = 2317.75
d = 0
-------------
Equation::
y = 36.5*sin(12(x+193.15))
------------

.
I = .

Plot I = 36.5*sin(2pi*30*t - (65.5/360)*2pi))
