Question 1115048: please help me answer the following question:
"Two voltages:
V1 = 6 cos(10t), V2 = 8 sin(10t)
are inputs to a circuit. Determine an expression for the output voltage, v, if this is given by:
V = V1 + V2 = A sin(10t + α)
i.e. determine the values of A and α, where α is in radians" Answer by math_helper(2461) (Show Source):
You can put this solution on YOUR website! a*cos(x) + b*sin(x) = c * sin(x + p)
c =
p = phase shift =
You have
a=6
b=8
(and x=10t which just gets carried along)
so you can plug in to find
——
To get the phase shift in radians: radians
