## new one...

Ok what if the equation is:

L * di/dt + (R1+R2)i + q/C = U

L = 4
R1 = 8
R2 = 6
C = 4
u= 10cos8t

i(0) = 1
i´(0) = 1

I must calculate i(t) and plot the answer i.

i(0) = 0
q(0) = 2

the answe should be:
q(t) = -3e-3 + 4e-2t + e-t

Is it possible to solve and plot?

## thank you....

Thank you. I appreciate it.

a) How can i use laplacetransform to solve the equation reference to i1, i2, i?

i1 = i2 + i
2i1 + i2 + 2i1 = 30 + 20cos5 + 114sin5
1/50 i3 + 4i3 - 2 i2 = 0

i1(0) = 0

i2(0)=0

i3(0)=0

b) Plott the equation.
