Answer:
The approximate total impedance is 7.32ohms
Step-by-step explanation:
The formula for finding the phase angle between the current and source voltage of a simple AC circuit is derived from the relationship:
Cos θ = R/Z
From the formula we can get impedance Z given θ and R
θ is the angle of the total impedance
R is the resistance
Z is the total impedance
Given θ = 35°
R = 6ohms
Z =?
Cos 35° = 6/Z
Z = 6/cos35°
Z = 6/0.819
Z = 7.32ohms

Answer:
y = In | cos(2x + c ) | + c
Step-by-step explanation:
y" + (y')^2 + 4 = 0
substituting u = y'
u' + u^2 + 4 = 0
hence : u' = - (u^2 + 4 )
= 1 ------- (1)
integrating both sides of the equation 1
x + c = hence u = -2 tan(2x + c )
remember u = y'
y' = -2 tan(2x + c) ------ (2)
integrating both sides of the equation 2
y = ∫
therefore Y = In | cosu | + c
y = In | cos(2x + c ) | + c
